Heh, Tome of Ancient Lore = all spells ever exist with the [Evil] descriptor if they can have it added (such as by adding Violate Spell or some such). Imagine, shredding on a guitar from a mountain top and producing an Apocalypse From The Sky...now that's bad ass.
Sounds like a Lollapalooza my brother and I went to, back in '96.
Soundgarden kept playing during a freakin' monsoon-level downpour. Not only did they keep playing, but Chris Cornell walked out right onto the edge of the stage, where he was getting hit full force by it, and turned his face up right into the rain. It was Epic.
