I admit- this is a kick ass debut metal album from Tool.  They started off perfectly and matured mentally and musically over the years dramatically.  Maynard menacingly drives out brutal forces of power with his divingly compelling vocal chords, as does the rest of the band backing him up with their eardrum-crushing guitar riffs at booming speed.  Maynard is( of course, DUH!)the frontman, Adam Jones on lead guitar, Paul D' Amour on bass and Danny Carey on drums.  I am naming the guys if you are new to this band, but I'm sure most or all of the reviewers on this Tool page own more than just ONE of their CD's.  Take my word for it, this one's a MUST HAVE!  Pick it up ASAP and see for yourself.
