Alexander's Ragtime Band was one of the first all-steel percussion bands in Trinidad and Tobago and is considered a forerunner of the steelband. The band was organised at the Big Yard in Newtown in western Port of Spain, and first emerged on Carnival Monday morning in 1939. Named for the film Alexander's Ragtime Band, the band was louder and more mobile than tamboo bamboo bands that were popular at the time, and represented a change in musicality. They inspired the rapid adoption of steel percussion by bands in Port of Spain, leading to the development of the steelpan.
