Presenting this project, the Milano Saxophone Quartet leads the public through a real Metamorphosis. The audience realizes the quartet’s sound-transformation, which shows, through the performance and the different styles, one of its main idiomatic characteristics i.e. the flexibility. The program begins with the “Quatuor op. 102″ by A. Glazunov, which in its history already presents the first metamorphosis. The composer, in fact, discovers the saxophone in a jazz club in Paris. It’s only when he listened the “Quatuor de la garde républicaine” that he decided to write for this chamber group. Glazunov was impressed by the ductility of the instrument and he described it with such interesting words: “I hardly believe that this is the same instrument we can listen in the Jazz music. The purity and sweetness of the sound wonders me!” After Glazunov’s sphere we move to a completely different style with the work “Tango virtuoso” by Thierry Escaich. The composer and organist Thierry Escaich composed for the saxophone quartet a chamber-music’s masterpiece, who let the instruments going through the dance-mood in the organ art. The program leaves us with the last metamorphosis: the “Slavonic Dances” by Dvorak. These are the clear testimony of how the folk music has developed in according to gain a very important role in the classical music repertoire .
