Mark Nadler is a New York City-based cabaret performer, actor, and comedic pianist. He has been described as "one of New York's most acclaimed singer/pianists"^[1] and a "virtuoso" of classical piano.^[2]

Nadler was born and raised in Waterloo, Iowa. He took an interest in Broadway musicals from a young age, and was a fan of Danny Kaye, Mahalia Jackson, Jimmy Durante, the Marx Brothers, and Bugs Bunny.^[3] At the age of ten, he began performing professionally at the Long Straw Saloon in Cedar Falls, Iowa.^[3] As the gay son of Jewish immigrants, he felt out of place in the American Midwest.^[4] He studied at the Interlochen Arts Academy in 1981^[5] before moving to Manhattan at age 17.

Nadler frequently has collaborated with singer KT Sullivan.^[6] He has written and performed in dozens of touring, Broadway, and off-Broadway productions, as well as on television programs. Some of his more notable productions include American Rhapsody in 1999, an off-Broadway revue based on George Gershwin that won the Manhattan Association of Cabarets Award for Outstanding Musical Revue and was nominated for a Drama Desk Award and two Lucille Lortel Awards;^[7] Red Light, an "opera in honky-tonk" co-written with Dawn Hampton, which also won a MAC Award;^[8] Tschaikovsky (and Other Russians), performed at the Algonquin Hotel and the American Conservatory Theater, among other venues, which won the 2003 Bistro Award;^[9] and Russian on the Side, based on the Ira Gershwin/Kurt Weill patter song "Tschaikowsky (and Other Russians)", which played the Edinburgh Festival Fringe and the Marines Memorial Theater in San Francisco, California.^[3]

In 2004, Nadler and his partner hosted a "Bark Mitzvah" for their wheaten terrier, Admiral Rufus K. Boom,^[10] as a commentary on the frivolity and excess of Bar Mitzvah engagements at which Nadler had performed earlier in his career.^[11]
