DIAGE Festival Skipped 2025. Its Comeback Song Is 21 Years Old.

Bangkok's biggest digital arts and electronic music festival is coming back after a year in storage, and it isn't announcing itself with a hyped young signing. It's a 21-year-old song, gutted and rebuilt by one of the city's most respected sound artists.

DIAGE Festival returns October 31 to November 1, 2026, at Cloud11, the creative complex on Sukhumvit near Phra Khanong. It's the event's first edition since 2024: 2025 came and went with no DIAGE at all. The festival debuted at TBA Show DC in November 2023, ran a follow-up called DIAGE Degree in November 2024 at Unformat Studio, then went quiet in 2025. Cloud11 is a new venue for it, and organizers say production is being tuned to European festival standards, which is the kind of claim you can only check once the doors open.

A 21-Year-Old Song Announces It

Instead of dropping a lineup poster, DIAGE marked its return with a piece of music: "Continental Affair (DIAGE Deconstruction)," a full rework of a track by Cyndi Seui, the stage name of Cesar B. de Guzman, a Thai-born Filipino producer who has been making electro-pop out of Bangkok since the mid-2000s. He co-founded the label Kitsch Cat and worked as a senior producer at Smallroom, one of Thailand's formative indie labels, before any of that; "Continental Affair" first appeared on his 2005 double LP Micro Bitz Life.

The rework comes from Koichi Shimizu, a Japanese sound artist who has lived in Bangkok since 2003 and designed sound for Apichatpong Weerasethakul's Uncle Boonmee Who Can Recall His Past Lives, the film that won the Palme d'Or in 2010. Vocals go to Thanachai "Pod" Ujjin, frontman of Thai alt-rock institution Moderndog. None of the three had worked together before this. The festival describes the new version as built around "Bangkok's vibrant contrasts, where chaos and beauty co-exist," which is either a mission statement or an accurate description of the Sukhumvit traffic outside the venue.

What DIAGE Actually Is

The 2023 debut packed more than 60 acts into three stages built for two different crowds at once: a DJ-facing bill that included Pangaea, Batu and Peter Van Hoesen, and an audiovisual program built around a live collaboration between Nosaj Thing and Daito Manabe. The 2024 follow-up, DIAGE Degree, brought in Caterina Barbieri and Ryoichi Kurokawa alongside Thai acts like JPBS, DuckUnit and Marmoset. The festival is still run by the same coalition that built it: multimedia studio SquareDots, promoters ZUBSCRIBE, design agency CHOUX LAB and the nightclub DECOMMUNE. Their pitch, in both editions, was digital art and electronic music sharing a room instead of competing for one, with daytime programming (talks, workshops, live coding) filling the hours between sets.

DIAGE isn't the only piece of Bangkok's small, stubborn audio infrastructure attempting something ambitious this year. Durian Radio is still streaming out of the back of a weed shop, and vocalist Pam Anantr just built her own sound room a few kilometers from Cloud11. None of it is coordinated. All of it is Bangkok refusing to let its underground shrink to fit a bad couple of years.

If You Go

Dates: October 31 to November 1, 2026 Venue: Cloud11, 888 Sukhumvit Road, Phra Khanong, Bangkok Tickets: Via diagefestival.com or EventPop; the 2026 artist lineup has not been announced

Organizers haven't said why 2025 got skipped, and nothing in the festival's messaging apologizes for it. What they've put out instead is a single that took a 2005 Thai-Filipino electro-pop deep cut, handed it to the man who scored a Palme d'Or winner, and got a Thai rock frontman to sing it. If the actual lineup, whenever it lands, matches that level of curatorial nerve, Bangkok's digital art crowd has a real reason to show up this time.
