Michael Bisio (March 4, 1955 Troy, New York) is an American jazz double bassist, composer, and bandleader.
Bisio has composed over one hundred works which have been performed in clubs, concert venues, and festivals.
In his book Jackson Street After Hours, music critic Paul de Barros called Bisio one of the heirs to Seattle's earthy yet innovative tradition and marked his compositional style as "a spare, bluesy sound, the sweet- and-sour timbres favored by Charles Mingus.
Beat Angel (2004), a film by Randy Allred with Vincent Balestri, features Bisio's compositions and improvisations.
In his film Time & Object, animator Bernard Roddy uses "Something Different" from Zebulon as the score.
