On Soulfly's 1997 self-titled debut disc, singer-guitarist Max Cavalera did little to hide the bitterness that stemmed from his acrimonious split with Sepultura, the influential Brazilian hard-core group he used to front. On "Eye for an Eye," the disc's first track, he declared, "I am what I create/ Believing in my fate/Integrity is my name/ All that I am doing/Can never be ruined/My song remains insane." His anger -- which came through in pontificating lyrics, primal beats, howling vocals, and grating guitars -- was only fueled by the confusion surrounding the murder (still unsolved) of his best friend/stepson. Cavalera didn't have to dig deep to find the open wounds of unresolved issues. On Soulfly's sophomore effort, Primitive
, he continues to vent, but has expanded his musical vision. Joined by various guests (Slipnot's Cory #8, Deftone's Chino, Slayer's Tom Araya, and singer Sean Lennon), Cavalera, who plays a four-string guitar that delivers a harsher sound than its six-string counterpart, melds a variety of diverse styles. The frenetic "Boom" and the instrumental, Dead Can Dance-sounding "Soulfly II" are clear digressions, and his collaboration with Cory #8 on "Jumpdafuckup" features bellowing vocals and razor-sharp guitar chords that are juxtaposed with melodic moments of serenity. And, even though Cavalera uses the word "fuck" more than a comedian on a Def Comedy Jam special, he's not swearing just for shock value; limited vocabulary or not, he remains one step ahead of most of today's major rap/metal players.
