I saw Krisiun when they played with morbid angel and Behemoth...and they are exactly what they were at that show, a good opener but not much more.
Old school SOILWORK is some of the best in its feild, Chainheart machine and steelbath suicide.
BEHEMOTH is some of the heaviest music out there right now, not the beat "hearable" vocals though.
A very small band out of kentuky is ABOMINANT, I'm obsessed with their album "ungodly" definately worth your time.
CALLENISH CIRCLE's "Forbidden Empathy" is a 2 disc compilation of all their early demos and cds. This band debuted around the same time as In Flames, similar style and easily just as good as early In Flames
THE CROWN, Deathrace King....buy it
