ArcTanGent Festival has lifted the curtain on its 2026 roster, serving up one of its most ambitious and genre defying bills to date.
The Bristol weekender, running August 19th through until 22nd will be led by Primus, Chelsea Wolfe, and the powerhouse pairing of Cult of Luna and Julie Christmas.
For a festival built on experimental heavy music, the lineup reads like a fever dream the scene has been working on for years. Primus finally landing at ArcTanGent feels like a long overdue collision of out there, technical brilliance.
Chelsea Wolfe’s headlining slot marks the comeback moment fans lost back in 2020 when COVID wiped out her originally scheduled appearance. Cult of Luna with Julie Christmas performing material tied to Mariner adds a milestone of its own, the album hits its 10 year anniversary next year, and the festival is treating that fact like an event all its own.
The bill goes deeper with new additions including Conjurer, SikTh, Napalm Death, and High On Fire, a spread that pulls from sludge, mathcore, grind, prog, and everything in the fringes between.
It’s the kind of lineup that defines ArcTanGent’s reputation as the UK’s home for the strange, the technical, and the boundary pushing.
Festival organiser James Scarlett shared his excitement, saying:
“The stars really have aligned for this set of ArcTanGent headliners – and it’s safe to say all three have been firmly at the top of our wish lists for a very, very long time. Primus at ArcTanGent is well overdue, Chelsea Wolfe can finally make that headliner appearance following the booking, announcement and then cancellation from back in 2020 due to Covid, and ‘Mariner’ by Cult of Luna and Julie Christmas is 100% one of the greatest albums of all time (and celebrating it’s 10th anniversary next year!). To have them all headline ATG in the same year is literally unbelievable – and we’re extremely proud to present a festival line up truly unlike anything else you’ll find on the planet.”
Tickets are officially on sale here.
