So for a period over the last two years I've been a part of a ska band. We were originally put together by our lead guitarist/singer, who reached out to our first trumpet, and we arranged most of the band through him. After a little while, we began playing shows, and over the course of the two years with the band we played many shows we got paid for, even with big ska acts like Reel Big Fish, the Toasters, and Streetlight Manifesto. We also recorded an album and got a bunch of merchandise, which we sold a significant quantity of at (in my opinion) rather inflated prices. During this time, nobody distributed the wealth, as it was going towards more merchandise, etc. and it was put into a collective bank account. A couple months ago, the lead singer/guitarist/founder decided to basically kick out half the band, myself included, without consulting with us first. I have since tried to contact him to get some of the money I left sunk in the band back, I think it makes sense, we were a big band but I played an important role in recording, performing, and improving our show, and invested a lot of time/money/talent without much return. He responded by telling me that I was mistaken in believing that I deserved money, and after a gently-worded and well thought out response from me, he started ignoring me completely. Am I wrong to believe he's stealing from me? Is there any way I can get a return on my investment?
<bot>: I think the guitarist from my band is trying to weasel me out of money I deserve, don't know what to do.
