So yesterday I hosted my second jam band. Sent out the email with the tune list 6 weeks ago. The guitarists were mostly learning the songs at the rehearsal, AND playing way too loudly. This was frustrating. The singer was really good. The drummer was a nice guy but didn't seem to have prepared the songs at all. So, the only people that really prepared for the jam was me and the singer. Not sure if I want to jam again. What would you do? Why can't people practice before coming to rehearsal? I know it's just a jam, but is it too much to ask people to practice ahead of time?
