In high school (I think I was 14), someone at my church asked me to play on her record. Her style was vastly different from mine, but it still sounded fun. She had piano, bass, drums and a few strings. We rehearsed in her living room for a few weeks. My drum parts were very minimal (and somewhat soft). The Carpenters rocked harder than we did.
We recorded in a metallic barn-like structure. We recorded the backing tracks in two days (about 6 hours per day). She and her husband paid me $75 for my time.
I never heard the record and I have no idea what her name was/is. I was happy with my compensation. Other than my earlier tale of woe, this was the least I was ever paid for a gig. Sadly, it was also the most. Everything else I've ever done was for free. I never claimed to be a genius.
