T. Rex were an English rock band, formed in 1967 by singer-songwriter and guitarist Marc Bolan. The band was initially called Tyrannosaurus Rex, and released four psychedelic folk albums under this name. In 1969, Bolan began to shift from the band's early acoustic sound to an electric one. The following year, he shortened their name to T. Rex. The 1970 release of the single "Ride a White Swan" marked the culmination of this development, and the group soon became a commercial success as part of the emerging glam rock scene.
