Dino Saluzzi is one of the world's most famous bandoneon soloists and composers, a master of delicate tones whose repertoire spans the entire musical palette from folk music through tango to jazz. He comes from the deep country of northern Argentina, and has always stressed his roots in a music-loving farming family. This is the starting point of Daniel Rosenfeld's unusual debut film, which he calls Essay on the Bandoneon and Three Brothers. He begins by showing Saluzzi on tour in Europe, recording the venues at which he performs: Venice, Bellinzona, Paris and Zurich. This is complemented by musings on the art of composition, Saluzzi's beginnings, background and yearning to compose. The mainly black-and-white footage is interspersed by a few colour pictures, portents of the second part of the film in which the director accompanies his star to his home town of Camposanto, an isolated settlement in Salta province, where Saluzzi was born in 1935.
