10 minutes is about as quick as most full bands can change over. There’s more involved than just getting the previous band off the stage. Most venues we play don’t backline drums so the previous bands drums need to be removed and the next bands drums set up and with mics in their place. The next band has to get their pedalboards plugged up, amps on, and line checked as well. But yeah 2-3 minutes to get the previous band off Is absolutely doable if people work together.
