April 20 street date. RECORD STORE DAY release. The only album credited to Marc Bolan & T. Rex and released in March 1974, "Zinc Alloy And The Hidden Riders Of Tomorrow" was the last T. Rex album to be produced by Tony Visconti, and features the autobiographical UK hit single "Teenage Dream". Recorded at Musicland Studios in Munich, Bolan was heavily influenced by his new relationship with songwriter Gloria Jones, and a new interest in black music that he heard on US radio stations while on tour in 1973. This 50th anniversary edition is presented as a zoetrope picture disc, based on the original limited edition multi-layered "lattice" sleeve. Viewed with a smartphone running a third party stroboscope app, the images appear animated. View all titles by this artist
