I was kinda affraid the songs can't be found on kazaa/imesh etc.
The bands are well known in the punk/hardcore scene and especially sick of it all has been going strong for nearly fifteen years now. On the websites of the bands you can probably find some mp3's. I'll search and post the links here as I find some. As for cd's check out your local alternative music store and you'll probably find a great deal there.
And if you're into the misfits you have to check out there new cd "project 1950" wich is a cover cd with only 50's r 'n' r songs , they play in the same formation as there tour. A true all-star line-up with Dez Cadena( ex-black flag) on guitar, Marky Ramone(ex-Ramones) on drum and Jerry Only on Bass/vocals.
Damn I'm hearing so much new rock bands from you guys, when I'll get to a musicstore soon I've got some work to do
