I haven't been able to find anything by them online, not even lyrics... but Chainsaw Kittens is very kickass. If you can't find anything to download by them online, you can IM me on AIM, SpriteInDisguise, and I'll send you a few of their songs.
Also, since I came to this community because of the common interest in Clann Zu, I'm assuming at least one of you listens to them? I'm trying to introduce them to my friends but they're not cooperating very well... hehe. ^^;;;
