Not sure if I'd call them typically conservative, but the Brando's lead singer, David Kincaid, is an active Civil War reenactor. It's hard to find lyrics much more conservative/reactionary than, "I am the keeper of the old ways..."
Lots of RUSH songs are libertarian/conservative (hence my screen name). But it seems later on it has become more liberal. Neil Peart’s book and blog writings I’ll read, until he bash’s some conservative person or idea. He can get pretty liberal, but they keep it out of the songs for the most part.
