...I know I make a lot of these 'recommendation' threads, buuut oh well. So yeah, I'm getting into punk and ska. And by punk, I mean real punk, not the crappy emo bands or pop rock bands people today consider punk. Bands like Reel Big Fish, Zebrahead, Black Flag, Bad Religion, Less Than Jake, Anti-Flag. Those are the kinds of bands I want to listen to. Buuut I'm not really into the whole "anti-usa/government" thing, so please try to stay from those kind of punk bands. Anti-Flag is an exception.
i dont listen to punk much, but i might be able to name a few. 30 seconds to mars, greenday, and my chemical are all pretty punk if you listen to their older stuff. also i don't know if you'd consider them punk, but mindless self indulgence is a good band too.
