Marc Bolan And T.Rex - Best of the 20th Century Boy (1986)

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.

From 1970 until 1973, T. Rex encountered a popularity in the UK comparable to that of the Beatles, with a run of eleven singles in the UK top ten. One of the most prominent acts in British popular culture, they scored four UK number one hits, "Hot Love", "Get It On", "Telegram Sam" and "Metal Guru". The band's 1971 album Electric Warrior received critical acclaim as a pioneering glam rock album. It reached number 1 in the UK. The 1972 follow-up, The Slider, entered the top 20 in the US. Following the release of "20th Century Boy" in 1973, which reached number three in the UK, T. Rex began to experience less commercial success but continued recording one album per year.

In 1977, Bolan died in a car crash several months after the release of the band's final studio album Dandy in the Underworld. Since then, T. Rex have continued to exert a vast influence on a variety of subsequent artists.
