Attended with great anticipation by Metalheads, Hellfest invites you to gather from Thursday, June 18 to Sunday, June 21, 2026, to shake the town of Clisson once again. Like every year, a crowd of festivalgoers camps out at the Main Stages. But if doom, stoner, or sludge are your jam, head to the Valley stage, where a host of acts awaits! Cult of Luna, Amenra, Mastodon... Here’s our pick of 5 must-see bands this summer on the Valley at Hellfest!

A not-to-be-missed festival for all lovers of extreme music, Hellfest will once again celebrate hard rock, thrash metal, black metal, heavy metal, doom, dark folk, classic rock and alternative rock over four days and evenings that promise to be as explosive as they are thunderous.

The 2026 edition, to be lived by festival-goers on Thursday 18, Friday 19, Saturday 20 and Sunday 21 June, promises thrilling musical moments thanks in particular to the presence of Iron Maiden, Megadeth, the Cavalera brothers, Anthrax, Alice Cooper, Behemoth, Deep Purple, Papa Roach and Limp Bizkit! A lineup of bands and artists to see and hear on the Mainstages (1 & 2). But Hellfest is also four other stages, including the Valley dedicated to doom, stoner, sludge, and experimental metal!

If you're a fan of these different musical styles, then you're likely to spend a good part of Hellfest in front of the Valley. That's why we've selected 5 bands and artists for you to see this summer in the Valley for the new edition of Hellfest.

It's worth remembering that the Valley has had a new location on the site since 2023. Gone is the marquee nestled near the Altar - Temple duo, and the Valley stage is now set up not far from the Warzone.

Hellfest 2026: 5 acts you can't miss on the Valley

Mastodon — Friday, June 19, 2026, from 11:50 p.m. to 12:50 a.m.
Progressive sludge — USA

A heads-up to sludge and stoner fans: Mastodon will be outside The Valley on Friday from 11:50 p.m. for a heavy dose of loud songs blending melodic lines, catchy riffs and commanding beats. This new set from the Atlanta-born American band is a chance to dive back into their rich discography. And we’ll naturally spare a thought for Brent Hinds, the singer and musician, who passed away in August 2025 after leaving the group a few months earlier, in March.


Psychonaut - Saturday, June 20, 2026, from 2:40 PM to 3:20 PM

Post Metal - Belgium

If you haven’t yet discovered this Belgian outfit, now’s the time to catch up. Psychonaut has already released three standout records, "Unfold the God Man" (2018), "Violate Consensus Reality" (2022) and "World Maker" (2025). This summer, the post-metal trio, made up of Stefan De Graef, Thomas Michiels and Harm Peters, rolls into the Valley stage at Hellfest, delivering a set that’s both spellbinding and explosive.


Amenra - Saturday, June 20, 2026, 9:40 PM–10:40 PM

Post Metal - Belgium

They too come from Belgium and are dead set on turning the Valley upside down this summer! Three years after their Hellfest show, Amenra return to Clisson, ready to again flood our ears with their labyrinthine yet devastating riffs and the anguished, furious voice of Colin H. van Eeckhout.


Cult of Luna - Saturday, June 20, 2026, 11:50 PM to 12:50 AM

Post-metal - Sweden

As a regular at Hellfest, the Swedish band Cult of Luna is returning to Clisson this year. Hailing from Umeå and formed in 1998 around Klas Rydberg on vocals and Johannes Persson on guitar, the group has since gone through lineup changes. Yet Cult of Luna still manages to delight our ears with its powerful blend of progressive metal, sludge, post-metal and doom.


Acid Bath - Sunday, June 21, 2026, 8:50–9:50 PM

Sludge - USA

Fans of Acid Bath are all smiles! The American sludge metal band formed in the early 1990s in Louisiana is reuniting and hitting the stage again this year. They’re set to open for several dates on System of a Down’s European tour. And that’s not all—the band will also be featuring at Hellfest this summer. A chance to rediscover this legendary outfit, whose career paused in 1997 after bassist Audie Pitre died in a road accident.

You probably guessed as much, but this list isn’t exhaustive, because many other bands and artists are scheduled on the Valley from June 18 to 21, 2026 at the Hellfest. And you, what have you planned to go see on the Valley this year in Clisson?
