Following the recent Rifftides review of Gretta Matassa’s new album, I came across a video that she made when she was in Los Angeles for an engagement. Her longtime bassist, the Seattle veteran Clipper Anderson, was on board. Her other sidemen for the occasion were pianist Mike Garson and drummer Bob Leatherbarrow, stalwarts of the Southern California jazz community. The Riffides staff thought that you would enjoy Ms. Matassa and friends in their medley of songs written by George and Ira Gershwin.
