I had a Drummer watch me play my entire set the other night.  This was at a rehearsal, and I have known this drummer for over 30 years.  Still, it can be a bit unnerving to have a colleague watch you work, staring at your every move.  We were kids when we met, and he didn’t play drums at the time.  Soon after, he started playing music, and that meant we would most likely never be in a band
