Punk is awesome, especially the more raucous anti-establishment punk bands of the days of yore... although I'm really not an expert on that type of music.
Favourite punk band is The Clash, and London Calling is one of my all-time favourite records. Also classic older stuff like Dead Kennedys, Discharge, I listen to pretty regularly.
Favourite current punk band is Propagandhi, and anyone who looked at the 2009 awards will know that I put their Supporting Caste as my top album of last year.

So much love for Propagandhi, goddamn these guys are underrated. Have you heard Failed States? Kicks all kinds of ass.
