The memorable cover of T. Rex’s second album, The Slider, has eye-shadowed and pancake-face-painted Mark Bolan wearing a stewpot over his head, and the album that cemented the band’s (and Bolan’s) position as the founder and leader of the glam-rock movement in the U.K. in the early 70s. The Slider (released July 21, 1972) was actually the sixth album for Bolan; on the first four with the full name Tyrannosaurus Rex he played hippy-psychedelic-folk-rock ballads and spacey, poetic numbers. But a shortened name and change in musical direction launched Bolan into his glam phase, which included enduring rock classics like “Hot Love,” “Bang A Gong (Get It On)” and “Metal Guru”, the latter coming from The Slider. Tragically, Bolan never got to enjoy his influence on glammers like David Bowie, glam-punkers like the New York Dolls, or hard rockers like Kiss. He died in a car accident in 1977. The Slider is available for purchase as a CD or individual mp3 files on Amazon, and as iPod tracks on iTunes. A Bolan/T. Rex playlist is in the works for Dr. Rock’s Playlist Vault.
