The series continues Friday, September 20, with Tom Griesgraber, Billy Galewood, and Steve Bulman. Billy Galewood is an American singer, songwriter, and rapper from Cleveland who ended up in California, where he continued to hone his eclectic acoustic/hip-hop sound. His shows blend hip-hop, acoustic rock, funk, improvisation, and comedy. Multi-instrumentalist-composer Tom Griesgraber is known for many roles, including behind the scenes, in the music industry, but the Berklee College of Music graduate is best known onstage for his mastery of the unusual Chapman Stick. The relatively narrow instrument produces music that to the uninitiated listener sounds like an ensemble. Those who have seen Griesgraber perform live, however, know that the sonorous music produced comes from the magic of a unique virtuoso. A seasoned guitar player of 30 years, Stephen Bulman specializes in percussive fingerstyle music. Known for his distinctive use of harmonics and pitch bending, his tranquil compositions create a soothing auditory experience.
