Pearl Jam setlists, their length and diversity from night to night, make other bands look like assholes. Almost no one treats their fans as good as PJ do, and frankly, there's no reason MANY bands, arena-level or not, can't do similar things at their own shows. Laziness is the only excuse. Take pride in ALL your material (PJ played fucking BUGS the other night for only the 2nd time ever b/c one of their oldest diehard fans put it on a setlist), learn it, rehearse it, and shake it up every night. THis goes for almost all metal bands too. No reason a band like LOG or Machinehead have to play the same shit every night.
