Obscene Extreme 2026 at the Bojiště complex in Trutnov, Czech Republic continues to build its sprawling extreme music gathering, with a growing roster that spans the full spectrum of heavy underground sounds. The July 1–5, 2026 festival has confirmed a wave of notable additions including Converge, Benighted, Eyehategod, Hideous Divinity, Rotten Sound, Necrot, Pro-Pain, The Dwarves, Nunslaughter, and many more.
Since 1999, Obscene Extreme has operated as a community-first, underground-first festival — a place where the artists and the audience share equal devotion to the music. It’s a very specific energy, and one that can’t be replicated. If you’ve never been, 2026 is as good a year as any to make the trip to Bohemia.
