The main title theme from "Last Tango in Paris" has been my favorite since I saw the film in its original theatrical release. Nothing tops the "waltz" version form the original soundtrack by Gato Barbieri:
Hola pericles, While there in September we heard the Gotan music being played in Corrientes all the time. We bought the Gotan Project Live (La Revancha del Tango y Lunatico Tour). We play that outloud when we are using the threadmill at home and it is awesome!
