Is it too early to start listing some good releases of 2011? Of course not! Sorry, I couldn't wait until December.
my favorites:
Spraynard - Funtitled
Copyrights - North Sentinel Island
Banner Pilot - Hear Beats Pacific
Against Me! - Black Crosses
Red City Radio - The Dangers of Standing Still
Direct Hit! - Domesplitter
Frank Turner - England Keep My Bones
The Wonder Years - Suburbia
I'm sure I'm missing quite a few, but I like those a ton. I haven't really had a time to really listen to the new Cobra Skulls album yet, but I'm sure it could make this list.
