Arctangent Festival have unveiled their lineup for 2026.

Primus, Chelsea Wolfe and Cult Of Luna & Julie Christmas will headline the event which takes place in Bristol from 19-22 August.
Other new names just added include Conjurer, SikTh, Napalm Death and High On Fire.
On the announcement, festival organiser James Scarlett says “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.”
