The English rock band T. Rex was formed in 1967 by Marc Bolan, the band’s singer-songwriter and guitarist. Under their original band name of Tyrannosaurus Rex, they released four psychedelic albums. From 1969 Bolan began to shift from an acoustic sound to an electric one and shortened the name to T. Rex. Bolan was killed in a car crash in 1977 shortly after the band’s final album Dandy in the Underworld. However, T. Rex has continued to exert influence on a variety of subsequent artists since then.
Released in 1973, 20th Century Boy and reached number 3 in the UK Singles Charts. It was also a bonus track on the reissue of the 1973 album Tanx.
