Michael Jay Feinstein (born September 7, 1956) is an American singer, pianist, and music revivalist. He is an interpreter of, and an anthropologist and archivist for, the repertoire known as the Great American Songbook. In 1988 he won a Drama Desk Special Award for celebrating American musical theatre songs. Feinstein is also a multi-platinum-selling, five-time Grammy-nominated recording artist.
Feinstein was born in Columbus, Ohio, the son of Florence Mazie (née Cohen), an amateur tap dancer, and Edward Feinstein, a sales executive for the Sara Lee Corporation and a former amateur singer. At the age of five, he studied piano for a couple of months until his teacher became angered that he wasn't reading the sheet music she gave him, since he was more comfortable playing by ear. As his mother saw no problem with her son's method, she took him out of lessons and allowed him to enjoy music his own way.
After graduating from high school, Feinstein worked in local piano bars for two years, moving to Los Angeles when he was 20. Through the widow of legendary concert pianist-actor Oscar Levant, in 1977 he was introduced to Ira Gershwin, who hired him to catalogue his extensive collection of phonograph records. The assignment led to six years of researching, cataloguing and preserving the unpublished sheet music and rare recordings in Gershwin's home, thus securing the legacy of not just Ira but also that of his composer brother George Gershwin, who had died four decades earlier. Feinstein's extended tenure enabled him to also get to know Gershwin's next-door neighbor, singer Rosemary Clooney, with whom Feinstein formed an intensely close friendship lasting until Clooney's death. Feinstein served as musical consultant for the 1983 Broadway show My One and Only, a musical pastiche of Gershwin tunes.
