Three small Seoul stages, one October: 15, 21 and 31

Three small Seoul stages host three very different October nights: an electronic-folk lineup in a Hongdae basement, a solo Bach recital, and a nine-piece band playing its new album. If you're in Seoul between mid and late October 2026, all three are close enough together to plan around.

Which three small Seoul shows fall on October 15, 21 and 31, 2026?

The three shows are 〈지하침공!〉 on Thursday 15 October at KT&G Sangsang Madang Hongdae Live Hall, pianist 손민수 (Son Min-soo) in 〈손민수 Curated 32〉 on Wednesday 21 October at Hyundai Card Understage, and the 단편선 순간들 (Danpyunsun and the Moments) release showcase for 《연인들》 on Saturday 31 October, also at Understage . The Korean listings magazine Popga recommended all three in a guide published on 8 October 2026. Tickets cost 44,000 won to 55,000 won, so seeing all three comes to 154,000 won before fees.

Quick Answer: Seoul has three small-venue concerts in October 2026. On 15 October, 지하침공! plays KT&G Sangsang Madang Hongdae (44,000 won). On 21 October, pianist 손민수 plays Bach at Hyundai Card Understage (55,000 won). On 31 October, 단편선 순간들 holds their 《연인들》 album showcase at Understage (55,000 won), according to Popga.

The three nights take place in two neighbourhoods. KT&G Sangsang Madang is in Hongdae, Mapo-gu, and Popga gives its address as 서울 마포구 어울마당로 65 . Hyundai Card Understage is underneath Hyundai Card Music Library on Itaewon-ro in the Hannam/Itaewon area. Popga lists its address as 서울 용산구 이태원로 246 . Both are small rooms, and two of the three shows have one price for every seat. The 15 October show has unreserved seating, so where you stand depends on when you arrive.

The table below lists the details for each night as Popga published them on 8 October 2026.

Where the details come from. Most of the facts in this plan come from one Popga article. Some are also confirmed by other sources:

• 15 October: A KT&G Sangsang Madang listing on ArtInsight confirms the date, the venue (basement level 2), the 44,000 won price for all seats and Melon Ticket as the seller . That listing does not name the performers, so the four names come from Popga only.
• 21 October: Hyundai Card's DIVE platform lists "10/21(수) 손민수 Curated 32" as a Bach Well-Tempered Clavier Book 1 recital at Understage . The start time, the 70-minute running time and the piece numbers 17–24 come from Popga.
• 31 October: Korean Vibe reported on 10 September 2026 that the band will release 《연인들》 on 15 October and hold the showcase at Understage on 31 October . The band's Instagram bio also lists the 10.31 Understage date. The 18:00 start, the price, the running time and the nine-player lineup come from Popga.

Popga is the only source for start times, running times and lineups, so check the seller's page (Melon Ticket or NOL Ticket) before you book or travel.

Thursday, Oct 15: What is 지하침공! at Sangsang Madang Hongdae?

지하침공! is a four-act, one-night show at KT&G Sangsang Madang's basement live hall in Hongdae on Thursday, 15 October 2026. According to Popga, the lineup is 최미루, MELKI, 보리 and eosa. The show starts at 20:00 and runs about 150 minutes. Tickets cost 44,000 won for unreserved seating and are sold through Melon Ticket . If you get there early you can pick your own spot, and a 20:00 start means it ends around 22:30.

The venue's own listing, posted on ArtInsight, backs up the core details. It gives the same date, places the show in the Live Hall on the second basement level of the Mapo-gu building, and lists one 44,000-won price for all seats on Melon Ticket. That listing does not name any performers, though. Popga is the only source for the four names above, so check the Melon Ticket page before you plan your night around one particular act.

The same listing explains the title, which means "underground invasion." It describes four musicians who work in electronic and folk music leaving a lecture room in the same building and taking over the basement venue. Expect a bill that moves between electronic and acoustic sets rather than one headliner with support acts. Neither source gives a set order or set lengths.

Here is what is known about each act:

• eosa and 최미루: a Joseilbo report on Sangsang Madang's debut-album program lists both among a group of new acts. Those acts released their first records through the indie distributor Mirrorball Music after finishing the program at Sangsang Madang's academy. For both of them, this show takes place in the building where they trained.
• MELKI and 보리: the research for this guide found no reliable background on either act. Their own channels or the Melon Ticket page are the best places to look before the show.

This is a show for listeners who like small rooms and newer names. If you follow K-indie releases more than arena tours, it shows how young Korean electronic and folk acts are being developed, at roughly the price of a club night.

KT&G Sangsang Madang Hongdae Live Hall | Concert venue

Sangsang Madang is KT&G's arts building in the Hongdae area. It houses a basement live hall, and the same building holds the academy classes that 지하침공! takes its concept from. The Live Hall is on the second basement level, according to the venue's ArtInsight listing. For this show, all tickets are unreserved.

📋 서울 마포구 어울마당로 65 (65 Eoulmadang-ro, Mapo-gu), Live Hall on B2 · 지하침공! starts at 20:00 on 15 October 2026 · 44,000 won, unreserved, about 150 minutes

💡 With unreserved seating, arrival time decides where you stand or sit. Leave enough time to find the B2 entrance. Plan your trip home too: the show should end around 22:30, close to the last trains.

Wednesday, Oct 21: What will 손민수 play at Curated 32?

At 손민수 Curated 32, pianist 손민수 (Son Min-soo) plays eight preludes and fugues from Bach's Well-Tempered Clavier. According to Popga, the program is Nos. 17–24 from Book 1 (〈평균율 클라비어 곡집〉 1권 중 전주곡과 푸가 제17~24번) . The concert is at Hyundai Card Understage on Wednesday, 21 October 2026, at 20:00. Popga lists it at about 70 minutes, with every seat at 55,000 won, sold through NOL Ticket .

Hyundai Card's own booking platform also lists the date. DIVE shows "10/21(수) 손민수 Curated 32" as a Book 1 recital of the Well-Tempered Clavier at Understage in Itaewon . In this case 손민수 is more than the performer. Hyundai Card's curator page names him as one of Understage's curators, the people who program the venue's Curated series . Popga describes this date as the series curator stepping onto the stage himself .

Keep your expectations accurate. This is a selection, not the complete cycle. In an earlier interview, 손민수 said that after his Goldberg Variations project he planned to perform the whole Well-Tempered Clavier: two books of 24 preludes and fugues each, 48 pieces in total . The 21 October program covers only the last eight pieces of Book 1. These are the paired preludes and fugues in the keys from A-flat major to B minor.

For a fan who came to Seoul for K-pop or indie bands, this night offers something different from the other two. Hongdae on 15 October is a long, unreserved-floor evening of electronic and folk music, and 31 October is a nine-piece band playing a full album. Curated 32 is about an hour with one person, one piano and no amplification. A small, music-focused room like Understage suits that kind of listening. You don't need any classical background to enjoy it: each prelude is short and freer in form, and each fugue that follows builds on a single theme in overlapping voices.

• Date and time: Wednesday, 21 October 2026, 20:00 (Popga)
• Program: Bach, Well-Tempered Clavier Book 1, preludes and fugues Nos. 17–24 (Popga)
• Length and price: about 70 minutes; 55,000 won for every seat; NOL Ticket (Popga)

Hyundai Card Understage | concert venue

Hyundai Card Understage is a small performance hall underneath Hyundai Card Music Library in Hannam-dong. Popga gives the venue address as 서울 용산구 이태원로 246 . The space runs the Curated series that this recital belongs to, and you will be back here on 31 October for the 단편선 순간들 showcase. According to Hyundai Card's Understage space page, online booking runs through the DIVE app, and when online tickets sell out there are no on-site sales .

📋 서울 용산구 이태원로 246 (246 Itaewon-ro, Yongsan-gu), below Hyundai Card Music Library · Curated 32 at 20:00 on 21 October 2026 · 55,000 won for every seat, about 70 minutes

💡 Payment at Understage is by credit or debit card only, and Hyundai Card holders get 10% off Curated shows. Check the current terms on DIVE before you book . A 70-minute recital that starts at 20:00 should finish by about 21:10, which leaves time for a late dinner in Hannam.

Saturday, Oct 31: What is the 단편선 순간들 《연인들》 showcase?

On Saturday, 31 October 2026, the band 단편선 순간들 (Danpyunsun and the Moments) holds a release showcase for its second full album, 《연인들》 ("Lovers"), at Hyundai Card Understage in Hannam. The album comes out on 15 October, about two weeks before the show . According to Popga, the band will play the whole album live . Of the three October shows, this is the only one built around a new release. That makes it the obvious choice for anyone who has followed the band since its debut.

Two sources confirm the date. Korean Vibe reported the album and showcase on 10 September 2026, the same day the band released the pre-release single '폭설 혹은 난시' ("Heavy Snow or Astigmatism") . The band's Instagram bio also lists the showcase at Understage on 10.31. The bio mentions a crowdfunding campaign for the album too, which ran until 6 October .

Popga is the only source so far for the details below, so treat them as Popga's listing and check the ticket page before you plan around them :

• Start time: 18:00, two hours earlier than the other two October shows.
• Running time: about 100–120 minutes.
• Ticket: 55,000 won for every seat, sold through Melon Ticket.
• Lineup: the five core members plus four guest players on flute, clarinet, percussion and chorus, nine musicians in total.
• CDs: general CD sales of 《연인들》 start on the showcase day, 31 October. Copies already set aside as crowdfunding rewards are shipped separately.

Nine people is a large group for a room the size of Understage. The added woodwinds and percussion suggest the arrangements will be fuller than the band's usual five-piece setup. Popga does not say how the stage will be laid out or whether there will be guest artists beyond these nine, so expect nothing more than the listing describes.

For newcomers, here is the band's background. Singer-songwriter 단편선 formed 단편선 순간들 in 2024. The members are 단편선 (vocals), 이보람 (piano), 송현우 (bass), 박재준 (drums) and 박장미 (guitar) . Their debut album, 《음악만세》, came out in September 2024 and won awards at the 22nd Korean Music Awards . 단편선 has described the new record as an open-ended project rather than a finished statement:

"이 음악이 모험을 통해 얻은 결실이라기 보다는 모험 그 자체로 느껴졌으면 한다." ("I hope this music feels like the adventure itself, rather than the fruit of an adventure.") — 단편선, vocalist and bandleader of 단편선 순간들 (source: Korean Vibe)

A practical tip: the album comes out on 15 October, the same night as 지하침공! in Hongdae, so you have about two weeks to get to know the songs before the showcase. With an 18:00 start and up to two hours of music, the show should finish between roughly 20:00 and 20:30. That leaves the rest of Halloween evening free, but Itaewon and Hannam will be crowded that night, so plan dinner and your route home before you arrive. Understage is the same venue covered in the Curated 32 entry above, so the payment rules listed there apply when you check this show's Melon Ticket page.

How do you get between Hongdae and Hannam, and where do you eat around each venue?

The two venues are on opposite sides of central Seoul, but one subway line connects them. KT&G Sangsang Madang is at 어울마당로 65 in Mapo-gu, in the Hongdae area . Hyundai Card Understage is at 이태원로 246 in Hannam-dong, Yongsan-gu , beneath the Hyundai Card Music Library (source: Hyundai Card DIVE, Understage). If you eat dinner early and leave yourself some slack, each night fits easily into one evening.

For Sangsang Madang, Sangsu Station on Line 6 and Hongik University Station (Line 2, AREX and the Gyeongui–Jungang Line) are both within walking distance. Understage is closest to Hangangjin Station on Line 6. Line 6 runs directly from Sangsu to Hangangjin with no transfer, so you can stay in Hongdae and still reach the Hannam shows without changing lines. Times change with service patterns and weekend schedules, so check the live route in Naver Map or Kakao Map before you leave rather than relying on a fixed estimate.

Eat around the start time. The 15 October and 21 October shows both start at 20:00, and the 31 October showcase starts at 18:00, according to Popga . A weekday 20:00 start leaves time for a normal dinner close by. The Saturday 18:00 start does not, so plan a late lunch or an early meal around 16:00–16:30, or eat after the show.

We haven't checked individual restaurants for these nights, so this section doesn't name any. Around Sangsang Madang, the streets between Sangsu and Hongik University stations are full of small casual places: noodle and rice shops, Korean barbecue and pubs. Many stay open well past 22:00. Yeonnam-dong, a short walk north-west, is quieter if you want to sit down before the show. In Hannam, Itaewon-ro and the side streets of Hannam-dong have cafés and mid-priced restaurants within walking distance of Understage. Expect higher prices than in Hongdae, and book ahead on a Saturday.

Plan each night in five steps: arrive, eat, queue or find your seat, watch the show, and get home. The running times come from Popga :

• Thu 15 Oct, 지하침공!, Hongdae: Eat by about 18:30. Seating is unreserved, so get to the basement entrance well before 20:00 if you care where you stand or sit. The show runs about 150 minutes, so it should end around 22:30. From there, Sangsu (Line 6) and Hongik University stations are a short walk away. Check last-train times on your map app if you're going to the outer districts.
• Wed 21 Oct, 손민수 Curated 32, Hannam: Have dinner in Hannam-dong at around 18:30–19:00 and walk to Understage before 20:00. The recital runs about 70 minutes, so you should be out by around 21:10. That's early enough for a drink nearby or an easy ride home on Line 6 from Hangangjin.
• Sat 31 Oct, 단편선 순간들 showcase, Hannam: Eat in the mid-afternoon and get to the venue before 18:00. The show runs about 100–120 minutes and should end around 20:00. This is Halloween night near Itaewon, so expect crowded streets and stations. Leaving through Hangangjin or by taxi toward the Han River side may be easier than walking up toward Itaewon Station. Check the route right before you head out.

If you're attending all three, staying near Sangsu or Hapjeong keeps you close to Sangsang Madang and on Line 6 for both Hannam nights, so all three trips are direct.

How do you book tickets, and what will the three nights cost?

Tickets for all three nights are sold online. You book the 15 and 31 October shows through Melon Ticket and the 21 October recital through NOL Ticket. Tickets for all three nights cost 154,000 won together: 44,000 won for 지하침공! and 55,000 won each for 손민수 Curated 32 and the 단편선 순간들 showcase . The rooms are small and each show has either unreserved seating or one price for every seat. Check availability on the seller's page before you plan the rest of the day.

Here is what each seller lists for each night:

• 15 Oct, 지하침공!: A KT&G Sangsang Madang listing on ArtInsight confirms Melon Ticket as the seller (prodId 213921) and 44,000 won for all seats. According to Popga, seating is unreserved .
• 21 Oct, 손민수 Curated 32: According to Popga, all seats are 55,000 won and sold through NOL Ticket .
• 31 Oct, 단편선 순간들 showcase: According to Popga, all seats are 55,000 won and sold through Melon Ticket .

Hyundai Card Understage, which hosts both Hannam nights, has its own booking rules. Hyundai Card's pages say Understage tickets are booked online through the DIVE app, and there are no on-site sales once online tickets sell out. Payment is by credit or debit card only, and paying with a Hyundai Card takes 10% off Curated shows . Popga lists outside sellers for both Understage dates, so check the listing on DIVE and the Understage venue page to confirm which channel and discount apply to each show. The 10% discount is described for Curated shows, which includes the 21 October recital. Don't assume it also covers the 31 October showcase.

Ticket prices and start times are from Popga's 8 October 2026 guide. The 15 October price is also confirmed by the venue's listing . Booking fees aren't included, and the Hyundai Card discount, if it applies, lowers only the 21 October ticket.

If you plan to buy the album on 31 October, budget for that separately. According to Popga, general CD sales of 《연인들》 start on the showcase day, except for copies sent out as funding rewards . Popga doesn't give a CD price, so check on the night.

Packing for late-October evenings in Seoul:

• Layers. Unreserved seating can mean waiting outside or on a staircase before doors open, and the 20:00 shows finish late. A light jacket you can carry inside works better than a heavy coat.
• A physical card. Understage takes card payment only, so carry a credit or debit card that works in Korea. Bring a Hyundai Card if you have one.
• Photo ID and your booking confirmation. Keep these handy in case staff ask for them when you collect tickets or enter.
• A charged phone. Tickets, the DIVE app and late-night transit apps all depend on it, especially on Halloween night in Itaewon.

Which night should you pick, and can you do all three?

Pick by the kind of music you want. Choose Thursday 15 October if you like electronic and folk experiments. Choose Wednesday 21 October for an hour of solo Bach piano. Choose Saturday 31 October for a full band playing a new album live. All three fit into one October trip. Two are weeknights, and the two Hannam shows are ten days apart. According to Popga, the three tickets cost 44,000 won, 55,000 won and 55,000 won, for a combined 154,000 won .

Here is how each night fits a different listener:

• Oct 15 · 지하침공! (Hongdae): This suits fans of small, unusual bills. KT&G Sangsang Madang's listing on ArtInsight describes it as four electronic and folk musicians "occupying" the basement hall . According to Popga, the lineup is 최미루, MELKI, 보리 and eosa. Popga also says seating is unreserved and the show runs 150 minutes .
• Oct 21 · 손민수 Curated 32 (Hannam): This is for listeners who want one pianist and a fixed program. According to Popga, 손민수 plays the preludes and fugues Nos. 17–24 from Book 1 of Bach's Well-Tempered Clavier, and the concert lasts 70 minutes . It is not a complete cycle of the work.
• Oct 31 · 단편선 순간들 《연인들》 showcase (Hannam): This is for fans of Korean indie rock who want to hear the new album in full. Korean Vibe reports that the album comes out on 15 October . According to Popga, nine musicians will play the whole record over 100–120 minutes .

To do all three, use this calendar:

1. Thu 15 Oct, Hongdae, 20:00. Plan for a late finish, since Popga lists a 150-minute run. Eat dinner before the show.
2. Wed 21 Oct, Hannam, 20:00. This is a short weeknight concert that should end around 21:10. You can go straight from work or a day of sightseeing.
3. Sat 31 Oct, Hannam, 18:00. This show starts earlier than the other two. It is also on a Saturday and on Halloween, when Itaewon gets crowded. Arrive early and plan your route home before you go. According to Popga, general CD sales of 《연인들》 start that day .

If you can only go to one, choose the night that matches what you came to Korea to hear, not the cheapest ticket. The price difference is only 11,000 won. Pick the Hongdae show for new indie artists, the Bach recital for focused classical listening, and the 단편선 순간들 showcase for a live album release.

All details are current as of 9 October 2026. Popga is the only source for the 15 October lineup, the start times, the running times, the Bach piece numbers and the nine-person band, so check these on the Melon Ticket, NOL Ticket or Hyundai Card DIVE pages before you book.
