I'm actually pretty big into Alt. Rock, Heavy Rock, and just about all Metal genres. The louder the better! XD
Electric Six is my absolute favorite right now, they're just out there as far as music goes. I've heard them described as everything from Indie to Disco Metal to Dance Rock to Alternative. They don't really take things too seriously and I love it.
Still good love for ACDC and the others. Even the 80's hair metal scene is fair game. Cinderella and Ratt, good stuff. ;3
