Nah... rehearsals are for drinking...

The group I'm with has taken to using our level check time with the sound guy as a fairly free flowing jam... Of course, it's not an open session. We're there to do a job, and since we're mostly playing festivals, the music attracts a crowd. We've had a few people come up and ask to play with us later (offstage), and we more than happily let them... you never know what you'll run into... But I guess that what we're doing before the show would qualify as a semi-justifiable 'elite' session.
