My feelings for the previous album Decadent Orgy of Atrocious Suffering from Texas one-man army Insidious Decrepancy was sort of lukewarm. On one hand I liked the brutality, but on the other I disliked the computer drums a lot so my expectations to The Inerrancy of Profanation was somewhat sceptic.
Again the programmed drums are the biggest issue, but it's clear that Shawn Whitaker has improved his skills. The drums sound less sterile and thin, but it's still quite clear they are programmed. It's not only with regard to the programming that progress has been made. The music is still very much brutal and technical death metal with references to Suffocation, Immolation, Severed Savoir and later day Death, but it appear more diverse than on Decadent Orgy of Atrocious Suffering. It seems very evident in tracks like "Befouling the Adoration of Christ" and "Enchanting Fantasies of Insurmountable Torment upon Innocence and Piety", not to mention the titletrack.
If you don't mind programmed drums then The Inerrancy of Profanation is not the worst place to look if you're on the lookout for some brutal death metal. It's clear that Insidious Decrepancy with The Inerrancy of Profanation have taken another leap forward. It simply doesn't come much more brutal than this.
