I am usually the one giving the workshop(photo) but it was certainly refreshing to go to a workshop and be on the other side of it all!  This was a great event put on by the Southern California Drum Society which seems to have a pretty active sereis of workshops.  The trio performing and teaching are, Bob Boss(guitar), Gunnar Biggs(bass), and Duncan Moore(drums).  Bob and Gunnar are my guitar and bass teachers.
