The Orquesta Hermanos Palau (Palau Brothers Orchestra) was one of the most renowned dance bands in Cuba during the early 1930s and late 1940s, following the tradition of local jazz bands started by the Jazz Band Sagua in 1914. These orchestras emerged as an influential sign of the American music in Cuba, to achieving a bridge between popular music genres and the characteristic sound of American jazz big bands.The original orchestra, which was founded in 1920, was originally known as Los Califates, but at the end of the decade changed its name to that of the Hermanos Palau. The decision was taken because five of its were all brothers. Manolo Palau was the pianist and leader, Felipe and Luis played trumpet, Rafael contrabass, and Raimundo served as saxophonist and co-leader.In 1931, the Palau Brothers orchestra appeared in the early sound film The Cuban Love Song, which was directed by W. S. Van Dyke and starred by Lawrence Tibbett, Lupe Vélez, Ernest Torrence and Jimmy Durante.  This film brought to the screen for the first time the famous tune The Peanut Vendor (El manisero), composed by Moisés Simons and performed by Ernesto Lecuona and the Palau Brothers' orchestra. After that, the orchestra toured extensively in South America and played mostly in the all white, up-scale venues. Their music ranged from jazz to popular, typical, and Afro-Cuban as well as classical. Among others there in the orchestra were the trumpeter Julio Cueva and the guarachero Cascarita (Orlando Guerra).The Palau musical tradition passed from brother to brother, and from them through their own families via their children, so much that the end of the 1950s they were able to organize another orchestra, known as Hermanos Palau Junior, to maintain their family tradition alive.
