I've been asked to sit in with a band I helped found in 2021. It was started as a duo then expended to 4 piece. Drums, bass, rhythm, and lead. I was lead, the band leader added another lead guitar for some reason. I left the outfit. I co-wrote two songs and the front man has offered me a chance to sit in on the studio recordings of those two songs.
I have no idea what this all entails. Anyone with experience?
