Let's make this short. My brother and I are musicians of about 10 years, him drums and myself bass/guitar. We have a recording studio that records bands in the area, and some of them have been asking us to fill in at their live gigs in the area. Usually these bands aren't getting paid at their gigs, though I can say that my brother and I are good musicians that will learn the material and play it on point and perform well. I don't want to keep giving our time and skills away for free, though I know that these bands don't have a large budget for these things. What would you TB'ers do in this situation? Thanks!
