Another great thing about this track. Sure it has that classic stuttering,staccato riff played in unison by guitar and bass. Lots of bands have tried over the years to play things like that. But what is even better are all the other guitar parts around that riff (not including the solo discussed above), which are very unusual for "hard rock", and the way the bass breaks free from the guitar on those parts. So cool and so unique. The bass lines are something else.
