From the description:
Also known as Michael Silverman, That 1 Guy is a Berkeley, Calif.-based, classically trained string bassist. After performing with some of the nation’s top progressive jazz ensembles throughout the 1990s, Silverman created an instrument out of wire and iron pipes that could serve his ever-expanding musical techniques. Think “gutbucket” bass with a lot more firepower. The result is an astonishing solo act. That 1 Guy’s influences include Captain Beefheart, Frank Zappa, Dr. Seuss, Rube Goldberg and Stanley Kubrick.
