The fusion between the string quartet, the perfect expression of the European 'classical' tradition, and the bandoneon, the musical embodiment of Argentina, is presented here in two quite different works. The Five Tango Sensations were originally written for Lutz Mommartz's experimental film Tango durch Deutschland. In 1989, Piazzolla resurrected five of the original seven pieces in response to a commission from the Kronos Quartet, renaming them Five Tango Sensations. This work occupies a special place in the ocean of Astor Piazzolla's music for two reasons: it is his only suite for bandoneon and string quartet, and it departs from the standard Piazzollian framework in both form and language. The suite Les Hommes de Piaf was originally a series of arrangements for string quartet and bandoneon based on tunes from the repertoire of Edith Piaf. But the composer's pen trumped the arranger's, imposing a texture in which the songs no longer play the leading role. Neither descriptive nor abstract, the suite Les Hommes de Piaf is merely a fantasised expression of states in which love can be by turns paradoxical, destructive, idealised, impossible or sensory, through a kaleidoscopic 'Piaf filter'.
