Yeah, I would be pissed, and I'd probably be doing something about it other than bitching and moaning on a message board, because I highly doubt that they're going to read your comment on here and suddenly decide to hand over your stuff, so you basically just end up sounding like a whiny little kid.
Yup, I'll continue to be wicked whiney until those pricks get a little reciprocity for what they did to me. I helped fund the recording, I wrote music and recorded on the record, gave them food, gas money, etc. In return, they deny my participation in the record, talk shit about me, and steal my shit. Lawyers cost money, which is something I don't have enough of to be able to do anything. So long as they do what they do, I'll do what I do. Like I said, if you don't like it, move along. No need to be a smarmy dick because you feel like I shouldn't post shit that relates to a band in this post.
