I recently auditioned for and got the bass part for a local indie rock group that does their own original music. The lead singer had some health issues and took several years to recover, and in the meantime, their bassist and drummer moved on to other things. They recorded a few albums, simply for the sake of remembering their music. They then decided to give it another shot, and now I'm the new bass player. We plan on touring regionally (on weekends) and playing locally about once a month. We already have money coming in from some plays we're getting on MTV and random other licensed stuff, but all that is being re-invested into the band. I'm seeing none of it, and rightly so for the time being. I've carved out my niche within the group already, and feel like a contributing member (even though they're sitting on about 40 original songs that I had no part in writing). My question: How does money work in a situation like this? I know for the time being that it makes sense for most or all of the money we make on CD sales, tv/movie plays, merch, and gig money will be re-invested back into the band. We've discussed that part. But what happens if we go on tour for a few months or something? Would I need an agent or do some type of negotiation to discuss how pay will be distributed? What happens if we "make it big"? I didn't start the band - I'm just the bass player, so I'm wondering what kind of cut I would get or how to determine what's what. Is there some standard for how all this works?
