DaDa is the eighth solo studio album by American singer Alice Cooper, released on September 28, 1983 by Warner Bros. Records. DaDa would be Cooper's last album until his sober re-emergence in 1986 with the album Constrictor. The album's theme is ambiguous, however, ongoing themes in the songs' lyrics suggest that the main character in question, Sonny, suffers from mental illness, resulting in the creation of many different personalities. The album alludes strongly to the dadaist movement. Its cover was based on a painting by surrealist artist Salvador Dalí titled Slave Market with the Disappearing Bust of Voltaire. Produced by long-time collaborator Bob Ezrin, at the time his first production with Cooper in six years, DaDa was recorded at ESP Studios in Buttonville, Ontario, Canada.
