Hey, get out your date books. I'm doing a gig Sunday afternoon, April 22, with my old pal (and honorary Co-Conspirator) Ben Schwendener, on piano, at an opening reception for Somerville Open Studios. (Click on Calendar for details.) Ben's a wonderful composer, pianist, and bandleader who's just released three books of his piano music for children. And included with each book is a CD of improvised performances of the pieces by his trio. Very cool stuff. (Visit www.benschwendener.com.) Ben's also my long-time teacher, and he played piano on, engineered, and nurtured my first CD, GOT THE MAP. He also played in a first version of the Co-Conspirators, with John on bass and Mike Connors on drums. Stop by and catch us on April 22, and check out some cool visual art too. Ben and I will do some songs from that first CD, plus a few new things. Hope to see ya. The price is right: FREE.
