I teach a studio recording class at APU. The students produce an EP, I oversee (hang out and drink coffee). Every semester I push the students to go get real players to play the session. Go get the best people you can find, and ask them to help you out. If you’re not getting told “No” at least a couple of times, you’re not asking players at the right level.
This year, one of the teams took that to heart. They pulled together the following players for rhythm section tracking:
