WHile we're on the subject of "punk", there's one thing that's always bugged me. When their "fans" give up on a band for "Selling out" it is seriously the most counter-productive and stubborn act of fandom ever.
It goes for all genre's of music, but especially in the punk world.
I'm a pretty progressive guy with my musical tastes, I dig (and encourage) when bands attempt to change it up a little bit and grow musically or lyrically. Sometimes it clicks with me and I really enjoy it and sometimes it doesn't, but I don't vilify them for trying.
People that expect bands who form when they're 20 to sound exactly like that in 10 years, 15 years (if you last that long) is idiotic. As are bands who actually do that, but that's another topic...
