Decca Records is a British record label established in 1929 by Edward Lewis. Its U.S. label was established in late 1934 by Lewis, American Decca's first president Jack Kapp and later American Decca president Milton Rackmil. In 1937, anticipating Nazi aggression leading to World War II, Lewis sold American Decca and the link between the UK and U.S. Decca labels was broken for several decades. The British label was renowned for its development of recording methods, while the American company developed the concept of cast albums in the musical genre.
