T. Rex / Tanx

Tanx is a 1973 album by rock band T. Rex, the eighth since their debut as Tyrannosaurus Rex in 1968, and the fourth under the moniker T. Rex. It was released on 16 March by record label EMI. Tanx was a musical departure from previous works: still containing tracks in the vein of The Slider, singer and songwriter Marc Bolan showed his interest for soul music, funk and gospel. Female backing singers appeared on a few tracks. New instruments such as mellotron were used, played by producer Tony Visconti, allowing the T. Rex sound to evolve.

Upon its release, Tanx was a commercial success. It peaked at number 4 in the UK Albums chart, number 3 in the German Albums chart and number 5 in Norway. No singles were released to promote the album.
