I don't really have a band. I've always really been a solo writer and then collaborated with singers. i.e. My "band" in my sig is just my stuff with a different singer and bassist.
So yeah, it'd probably be just me and him. I'm not sure if I'll sing yet or not. Might have to hire another vocalist. I doubt Michael will offer to sing for me.
Studio rent isn't bad because the studio is in his house. I'm looking at $1500 per song to track with him. On top of that I have to hire a drummer and a drum studio, so probably $600ish a day for that. Then mastering costs after that.
