Unicorn – Album Overview Tyrannosaurus Rex’s third studio album, Unicorn, arrived in May 1969 as their most intricate and mystical work to date — a dense tapestry of psychedelic folk, mythic storytelling and increasingly ambitious arrangements. Recorded at Trident Studios, the album captured Marc Bolan and Steve Peregrin Took at the height of their acoustic, otherworldly partnership, just before their creative split later that year. Released on 16 May 1969 by Regal Zonophone
