The Cradle Will Rock is a 1937 play in music by Marc Blitzstein. Originally a part of the Federal Theatre Project, it was directed by Orson Welles and produced by John Houseman. A Brechtian allegory of corruption and corporate greed, it includes a panoply of societal figures. Set in "Steeltown, USA", it follows the efforts of Larry Foreman to unionize the town's workers and combat wicked, greedy businessman Mr. Mister, who controls the town's factory, press, church and social organization. The piece is almost entirely sung-through, giving it many operatic qualities, although Blitzstein included popular song styles of the time.
