Oh man, I can talk about punk for hours. First got into it back in the 7th grade and I've been a fan since.
I'm not really as into it as I was in middle school and all throughout my high school years (been more into 80s/90s indie rock and old school rap in the past few years), but I still find myself listening to all my old favorite punk albums all the damn time.
When it comes to punk I pretty much love it all, but I definitely like early 80s hardcore(Zero Boys, Bad Brains, Minor Threat, MDC, Reagan Youth, JFA, Articles of Faith, Dayglo Abortions, etc) and early/mid 90's punk the most (Crimpshrine, screeching weasel, Mr. T Experience, J Church, Gaunt, Sicko, Scared Of Chaka, Dillinger Four, Discount, Radon, Tiltwheel, Leatherface, etc). There were so many good bands that came out of the early/mid 90s that definitely got overlooked a lot.
Also, my favorite punk band of all time would probably have to be Jawbreaker, so I also love any Jawbreakerish sounding band.
I love Jawbreaker.
You'd like Rites of Spring a lot - don't know if you're into them. They have 2 members that went on to play in Fugazi and Ian MacKaye produced them. Just that weird post-hardcore sound that really rocks. The D.C. Scene has always brought on some really unique awesome sounds.
Husker Du too.
Both of these bands are seriously ahead of their time.
They wrote this shit in 85 - rings more true today than it did back then.
