For some reason, it seems that being a nerd can help you play epic music. TVTropes calls it Heavy Mithril.
Ozzy yells about wizards:
"Evil power disappears / Demons worry when the wizard is near"
And yells about spaceships and fleeing an apocalyptic Earth:
"Rocket engines burning fuel so fast / Up into the night sky they blast"
Led Zeppelin, meanwhile, has been reading their Tolkien:
"Twas in the darkest depths of Mordor, I met a girl so fair
But Gollum, and the Evil One, crept up and stole away with her"
But, for the ultimate nerdy songs, how about having an astrophysicist playing guitar. Queen does in Brian May. In '39, they sing about RELATIVISTIC TIME DILATION:
"For so many years have gone/though I'm older but a year"
