Black Sabbath is one of my all-time favorite bands, and is one of the only metal bands I actually like. I've been thinking lately though that I should try listening to Rush more (especially as an amateur bass player, I could learn a thing or two from Geddy).
Comparing Prog Rock to your generic metal band
lmao.
Progressive takes some effort to create, and to play. Listen to 2112 and then listen to Black Sabbath.
May as well be comparing Jaco Pastorius to Mike Dirnt
