The only album credited to Marc Bolan and T. Rex and released in March 1974, Zinc Alloy was the last T. Rex album to be produced by Tony Visconti, and features the autobiographical 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.
