Libertango is [bad word] by [bad word] Ástor Piazzolla, published in 1974. The title is a portmanteau merging "Libertad" (Spanish for liberty) and "Tango", symbolizing Piazzolla's break from Classical Tango to Tango Nuevo.[1]

Grace Jones's song I've Seen That Face Before (Libertango) uses the same music, as does Jazz Mandolin Project's song "Jungle Tango", Guy Marchand's song "Moi je suis tango" and Kati Kovács's song Hívlak.

In 2002, a re-recording of Libertango appeared on Australian/British classical crossover string quartet Bond second album "Shine".
