T. Rex were originally known as Tyrannosaurus Rex from 1967. Name changed to T. Rex in 1970.
T. Rex's frontman was born Mark Feld, who changed his name to Toby Tyler, then Marc Riggs, Marc Bowland and eventually Marc Bolan.
T. Rex were an English glam rock band, formed in 1967 by singer-songwriter and guitarist Marc Bolan. The band initially called Tyrannosaurus Rex, released four folk albums under this banner. In 1970, Bolan began to make a shift from basing his band's sound around an acoustic guitar to basing it around an electric one and shortened their name to T. Rex. "Ride a White Swan" coincided with this change and instantly became a commercial success. From 1970 until 1973, T. Rex encountered in the UK a popularity unseen since the demise of the Beatles, with a run of 11 singles ranked in the British top ten. 1971's Electric Warrior received sustained critical acclaim as a pioneering album of glam rock. It reached the number 1 position in the UK. The follow-up, 1972's The Slider, allowed the band to enter in the top 5 in the USA. At the end of 1973, T. Rex started to have less commercial success but kept on recording one album per year.
In 1977, Bolan died in a car accident a couple of months after releasing their final studio album Dandy in the Underworld. Since then, T. Rex have continued to exert a vast influence on a variety of subsequent artists.
