A band that, since their triumphant debut in 1991, "Dawn of Possession", has taken the world of extreme metal by surprise with their dissonantly menacing riffs, combinations of massive rhythmic explosions, Bob Vigna's pitch harmonic guitar playing that determines sharp changes in tempo, or vocalist Ross Dolan's deep yet comprehensible growl. A band that in its three and a half decades of existence has built a reputation as a hard-working, intensively touring and tight-as-hell live band. 

A band that has lyrically focused on the dark side of humanity in all of their 11 released albums, be it religion or politics, both of which divide society to gain control over people. The band, which since 2010 has transferred to the Nuclear Blast, under whose banner they have released four albums increasing their ferocity, intensity and technical brilliance. The celebration of the OEF 25th anniversary will be as grandiose, triumphant and intense as is the live performance of this legend - IMMOLATION!!!
