Michael Gibson (Orchestrations) is represented on Broadway with Barnum and Woman of the Year, starring Lauren Bacall. Other Broadway credits include Peter Pan, The Andrew Sisters in Over Here!, and several flops he'd rather not remember. He worked on the original Grease and orchestrated the film version. He has composed several film scores and has recorded with James Brown, Gladys Knight & The Pips and Smokey Robinson.

Gibson's work on Dreamgirls went without Broadway credit when Harold Wheeler was brought in to reorchestrate (although he was credited in Boston programs). On Broadway, he has orchestrated the Patti LuPone revival of Anything Goes, Kiss of the Spider Woman, Steel Pier, You're A Good Man, Charlie Brown, and the currently-running Cabaret.
