Mike Silverman, better known as That 1 Guy, is an American musician based in Las Vegas, Nevada. He frequently performs and records as a one-man band, singing and using a variety of homemade musical instruments. Silverman is a classically trained double bass player who attended the San Francisco Conservatory of Music and developed a career in the progressive jazz scene in the 1990s, performing live and as a studio musician. He started out in a funk, rockabilly, jazz band called "The Fabulous Hedgehogs" before he developed his own style of solo playing and gained a reputation as a one-man rhythm section, incorporating traditional and slap-bass playing with percussive elements using the body of the instrument. When he began to feel limited by his instrument and a heavy schedule of playing and recording for other people, he started to devise a new instrument that would allow him the range to create his own music.
