Dealing exclusively in old-school basic Death Metal, Immolation boasted nary a melody or a subtlety. The band had scarcely changed over the years since their 1988 and 1989 demos Demo '88 and Demo '89. In 1991 their brutal assault came in the form of Dawn Of Possession under the membership of Ross Dolan (vocals/bass), Robert Vigna (guitar), Tom Wilkinson (guitar) and Neol Boback (drums; Craig Smilowski replaced him in 1996), an album of brutal uncompromising Death that was finally followed by a compilation of all their early demo work entitled Stepping On Angels... Before Dawn (1994), Here In After (1996).
Alex Hernandez replaced Smilowski for the subsequent albums of Failures For Gods (1999), Close To A World Below (2000) and Unholy Cult (2002). Close To A World Below also saw a membership change of Bill Taylor take over from Wilkinson. Stepping On Angels... Before Dawn re-release and Harnessing Ruin arrived in 2004 & 2005 respectively.
