I am all for the credential of playing on recordings, but this really sounds like a deal where I need to be paid for my time. This was a response to CL's ad I sent out over a month ago. Vocalist and guitarist want to do some tracks this Thursday and Friday, have a gig (no mention of me being on the gig). Want me to audition/rehearse tomorrow afternoon. So, get this email re: time commitment: We were thinking around 7 on thurs and 5 or 6 on fri. Note: they are referring to hours here. I have another commitment Thurs evening. No, I do not even know these people, although they appear to be good players from their site, but would do it for $$. What could I charge, or is some kind of recording credential a really good thing? I have some recordings of my own, but some quality recordings of being a sideman with others would be great too.
