Tanx is the eighth album by British rock band T. Rex, released in 1973. Tanx was a hit in UK and Europe but it failed to emulate the success of The Slider in the U.S., reaching only #102 in the album charts. It was critically derided by journalists who said the darker, adult sound was a complete departure from the unique melodic rock and roll that made the band famous. It predates punk in some ways, as 9 of the songs are less than three minutes long (by comparison, "Get It On" was 4:24), and "Shock Rock" is 1:43. The song "Born to Boogie" was actually not featured in the 1972 Ringo Starr produced film, also called Born to Boogie. This is seen by many as the beginning of the end for the band, both in personnel and the quality and success of the ensuing output.
