Borderline masturbatory guitar work? Absolutely. Does it kick ass? Hell yeah \m/ While far from the band's best work IMO, the songwriting makes some interesting decisions (beyond just being basic 4/4 thrash grooves and power chords), which undoubtedly went on to inspire an entire generation of heavy rock musicians - not to mention Judas Priest, who went on to further refine the sound of 80s thrash metal.
