A Beard of Stars is the fourth album by Tyrannosaurus Rex, comprising Marc Bolan (vocals, guitar, organ, bass) and the first with new partner Mickey Finn (percussion). It is notable for being the first album on which Bolan used electric guitars (although these had first appeared on the 1969 single King of the Rumbling Spires/Do You Remember.)
Four tracks from this album, including Great Horse were salvaged from Spring 1969 sessions for a fourth album with original percussionist Steve Peregrin Took in the wake of King of the Rumbling Spires. These four tracks were overdubbed for release by Finn, Bolan and Visconti. A further four tracks from the Took sessions – rejected for the final album – would subsequently surface on various compilations – three (Once Upon The Seas of Abysinnia, Blessed Wild Apple Girl, Demon Queen) in Bolan's lifetime, the fourth (Ill Starred Man) posthumously.
