Pablo Sorozábal Mariezcurrena (18 September 1897 – 26 December 1988[1]) was a Spanish composer of zarzuelas, operas, symphonic works, and the popular romanza, "No puede ser".

Trained in San Sebastián, Madrid and Leipzig; then in Berlin, where he preferred Friedrich Koch as composition teacher to Arnold Schoenberg, whose theories he disliked.

Sorozábal's liberal sympathies left him somewhat isolated after the Spanish Civil War, and many of his later zarzuelas were first seen outside the capital or in less prestigious Madrid theatres.

They include the ambitious, allegorical romance Black, el payaso (1942) and the ski-sports musical Don Manolito (1943), both of which starred popular Basque soprano Pepita Embil.

His tenure as director of the Madrid Symphony Orchestra ended abruptly in 1952 when he was refused permission to conduct Shostakovich’s Leningrad Symphony; and though his musical comedy Las de Caín was premiered at the Teatro de la Zarzuela in 1958, the opera Juan José had to wait for its belated (and highly successful) concert premiere until February 2009, after a full production was suspended during rehearsals in Madrid during 1979.
