The Michael Nyman Band, formerly known as the Campiello Band, is a group formed as a street band for a 1976 production of Carlo Goldoni's 1756 play, Il Campiello directed by Bill Bryden at the Old Vic. The band did not wish to break up after the production ended, so its director, Michael Nyman, began composing music for the group to perform, beginning with "In Re Don Giovanni", written in 1977.
