Punk has changed a lot since my skate punk days. For instance, I loved the way the singer in None More Black. He had this raspy voice that I had never really heard that much in my previous punk rock listening experience. Of course since then I have gone back and listened to some of the original bands that did this same kind of awesomesinging. See Jawbreaker and Hot Water Music.
Folk punk came outta nowhere and punched me in the dick. Against Me! writes songs that you can't help but sing along and get drunk to.
I was blown away by the bass and guitar in A Wilhelm Scream. They're like the next level Strung Out.
Polar Bear Club. Post-grunge/punk rock/melodic hardcore goodness. ITS.NOT.WORTH.LISTING.GENRES.AT.THIS.POINT.
Bomb the Music Industry! has been my favorite for the past three or so years. BTMI! proved to me that you don't need money to start a band, or make an album. BTMI! frontman Jeff Rosenstock recorded nearly all BTMI!'s albums for next to nothing. They embrace the DIY attitude like no other band I've ever seen.
And Banner Pilot just because.
