Astor Piazzolla
Astor Piazzolla (1921-1992) was an Argentine composer and bandoneon player, and one of the worlds foremost proponents of tango.
His style was known as neuvo tango, a revision of the traditional dance exemplified in one of his most famous works, Libertango.
He wrote many ensemble tangos and film scores, and this website features accompaniment tracks for Piazzollas Oblivion, which is an excerpt from his score to the film Enrico IV (Henry the Fourth). A link can be found below.
