Arctangent Festival

 Eyesore Merch is stoked to unveil another new collaboration for 2025, teaming up with one of the UK's most forward thinking and eclectic events - the mighty ArcTanGent Festival, held in Bristol in August!

 

Showcasing some of the most interesting and exciting artists from around the world, the festival brings together fans of everything progressive, leftfield and experimental with a killer line up of the weird and the wonderful.

 

This year's line up is a landmark collection, featuring the likes of Wardruna, Tesseract, Melvins, Karnivool, Green Lung and Mew featured alongside many other great artists. To say the billing this year is incredible barely does it justice!

 

Eyesore Merch can't wait to visit the festival this summer, and we look forward to meeting as many of you as possible over the course of four fabulous days of out-there entertainment!

 

In the meantime, why not browse our epic selection of official band merch, featuring bands from ATG's past and present?

ArcTanGent Festival 2026 – Official Band Merch from Eyesore Merch

Mathy riffs. Post-rock crescendos. Experimental brilliance. ArcTanGent returns to Fernhill Farm for another weekend of genre-bending heavy and weird (the good kind). If you like your guitars angular, your drums busy, and your sets unforgettable, you’re in the right place.

As always, Eyesore Merch will be on-site throughout the festival with a stacked selection of 100% official band merchandise — perfect for repping favourites, grabbing something from a new discovery, and heading home with more tees than you packed (standard).

ArcTanGent 2026 dates & location

19–22 August 2026 at Fernhill Farm, Compton Martin (near Bristol), BS40 6LD. A compact site, big sound, and a properly curated line-up spanning prog, math, post, hardcore, experimental rock and electronic.

Headliners & key moments for 2026

Primus

Off-kilter grooves and cult-hero status — Primus at ArcTanGent is the sort of booking that makes the whole weekend feel a bit special.

Chelsea Wolfe

Heavy atmosphere, haunting melodies, and a set that’ll stop you in your tracks. Expect something intense, immersive, and absolutely worth the walk across site.

Cult of Luna & Julie Christmas – Mariner (10th anniversary)

A landmark collaboration, performed as it should be: loud, cinematic, and totally absorbing. If you’re a “stand still and feel it in your ribs” kind of fan, this one’s for you.

Festival highlights

Curated, discovery-friendly programming

ArcTanGent is famous for the depth of its bill — you’ll find new favourites everywhere, from rising heavy hitters to niche legends. It’s the kind of festival where your “accidental” set becomes your favourite of the weekend.

Great food, independent drinks & late-night fun

Plenty of quality traders, proper choice behind the bars, and a strong “we’re all in this together” vibe. And yes — nights end in the silent disco, because ATG wouldn’t be ATG without it.
