Everyone should definately check out the current Deep Purple lineup
+1!
They're one of the very few "old" bands that isn't just going through the motions and touring with a second drummer, three backup singers and an army of auxiliary keyboard players. And as people, they've grown old gracefully instead of turning into cartoons of themselves like Whitesnake and Aerosmith.
Funnily enough, I was listening to the remastered
Burn last night, and I read that they're remastering
Stormbringer for release next spring. :D
