Waltari to Perform Death Metal Symphony with Full Orchestra at Brutal Assault 2026

Brutal Assault 2026 announces one of its most ambitious special performances

Brutal Assault 2026 has unveiled one of the most unusual and ambitious performances on its upcoming lineup.

Finnish visionaries Waltari will arrive at Josefov Fortress to celebrate 30 years of Yeah! Yeah! Die! Die! Death Metal Symphony in Deep C with a special anniversary concert joined by the Bohemian Symphony Orchestra Prague.

According to the festival, this will be one of the most technically and artistically complex productions in its 30-year history. 

Waltari’s Death Metal Symphony remains a landmark release

When Waltari released Yeah! Yeah! Die! Die! Death Metal Symphony in Deep C in 1995, the album stood out immediately for doing something few bands would have dared at the time.

The project fused death metal, symphonic scale and operatic elements in a way that felt radical rather than decorative.

More than a crossover experiment, it became a statement about how far heavy music could stretch without losing force.  

Brutal Assault will host the only global anniversary celebration of the album

This year marks 30 years since the release of that landmark work, and Brutal Assault 2026 will host what the organizers describe as the only global anniversary celebration of the album.

Waltari will perform the piece with a special lineup prepared exclusively for this occasion, giving the performance a sense of rarity that goes beyond a normal festival booking.

The Bohemian Symphony Orchestra Prague adds scale to an already unique event

To bring the project to life on the scale it demands, Waltari will be joined by the Bohemian Symphony Orchestra Prague.

The combination of heavy riffs, dense rhythms and full orchestral backing promises one of the most elaborate audiovisual moments on the Brutal Assault 2026 program.

It also fits the festival’s long-standing identity as a place where heavy music can take ambitious and unconventional forms.

Waltari could become one of the defining moments of Brutal Assault 2026

With so many strong names already on the bill, Brutal Assault 2026 hardly needed another selling point.

But Waltari performing Death Metal Symphony in Deep C with a full orchestra may end up becoming one of the edition’s true signature moments: rare, ambitious and impossible to confuse with a routine festival set.
