ArcTanGent, the UK’s premier festival for experimental rock, mathcore, and post-rock, has dropped another round of lineup announcements for its 2025 edition—and it’s already shaping up to be a standout year. The latest additions bring an exciting mix of heavy hitters, exclusive performances, and genre-defying acts, making this a must-see for fans of forward-thinking, boundary-pushing music.
Among the most anticipated names are Maybeshewill, the Leicester-born post-rock heroes who have consistently captivated fans with their cinematic, dynamic sound. Joining them are Frontierer, the genre-mashing mathcore outfit known for their blistering intensity and complex structures, and Mclusky, the Welsh post-hardcore veterans who are returning with a vengeance, set to release their first album in over a decade, The World Is Still Here and So Are We, this May via Mike Patton’s Ipecac label. Their inclusion will no doubt draw long-time fans and newcomers alike.
However, the surprises don’t stop there. ArcTanGent will host a rare UK appearance by God Is An Astronaut, the Irish post-rock pioneers, who are bringing their immersive, electronic-infused sound to the festival for an exclusive performance. The band’s ability to blend serene beauty with raw, cosmic power is sure to resonate in the festival’s distinctive setting.
Also joining the 2025 lineup are The Callous Daoboys, the Atlanta-based sextet whose genre-defying, chaotic energy has earned them a recent spot on the cover of Kerrang! Their unrelenting fusion of metal, punk, and experimental sounds will make for an unforgettable festival exclusive.
The festival is also stepping up its late-night offerings with an impressive slate of silent disco performances. Nordic Giants, known for their ethereal, cinematic live shows, will bring their atmospheric vibe to the silent disco, while AK/DK will deliver their experimental electronic beats. Yard, with their abrasive and energetic sound, and JOHN CXNNOR, performing an exclusive Doom Rave DJ-set, will further elevate the festival’s late-night energy.
