Ipecac has set an October 29 release date for Mutation's "Error 500", an album willfully devious, devilishly out of line and sonically uninhibited.

Drawing musicians from a ménage of disciplines and repute, Mutation is a band unlike any other, counting amongst their ranks Shane Embury (Napalm Death), David "Ginger" Walls (The Wildhearts) and Jon Poole (Cardiacs), with guest appearances from Mark E. Smith (The Fall) and Merzbow. The resulting reaction is an eight-man beast that exists to challenge the listener's preconceived ideas of extreme music, steeped in volatility, and wholly unapologetic.

Mutation began as a need to hear an album that no one else looked likely to make. An album that wallowed in sheer grindcore brutality whilst allowing it to be lifted by twisted talons of melodic majesty, and, with no loyalty to genre, delves into darker recesses of sonic experimentation. "Error 500" strikes you first by its personnel, and then exponentially more by the music itself, rewarding your attention with a white knuckle ride that travels at blast-beat speed along rails of industrial mayhem, thrilling with break neck twists and hyper rhythmic turns, guaranteed to leave you breathless and baying for more.

Intense and entirely random, this is an album to be loved by fans of all genres of experimental and extreme music, but especially by the type of listener that needs the parameters shifted a little more to the left.

If you're waiting for the next step in the evolution of extreme music, then look no further.
