Formed in 1991, the band has evolved through many incarnations, three Tone Cool and two self-produced CDs, trips around the world as far as South Africa and mostly the joys of playing a lot of music on Martha’s Vineyard where most of them live. The band started out as a four-piece with no piano, became a five-piece for several years, and then returned to a four-piece configuration, this time with no bass, and it’s been that way for over 10 years.
