Here's some of the stuff I'm listening to right now. Not necessarily my all time favourites but what seems to be getting played a bunch lately.
Psychostick - Fun
Messer Chups - Russian, psychobilly madness
Leng Tch'e - RAGE!
FEAR - Good ol' Lee Ving
Slayer - No description necessary
Carnifex - :D
Dayglo Abortions - Still as fun as when I was 14
Electric Six - These guys are just frickin' funny
Dead Mans Bones - Surprisingly enough Ryan Gosling's band is actually pretty cool
