The problem is Sepultura had already gone to shit even when max was in the band. Roots and Chaos AD were groove laden feces that suck on all levels.
The difference with Cannibal Corpse was they never changed their core sound. Sure some dynamics changed with the vocalist no longer being the premier lyricist, but overall they never succumbed to any trend.
I could DIIIIIIIIE! Or worse, DIIIIIIIIIIIIE!
