Polyphonic division and fusioning sounds are both so thrilling playgrounds when the four saxophones of the internationally leading saxophone quartet SIGMA PROJECT take care of music that knows about the especially high variability of these instruments. When I first heard SIGMA’s interpretation of Alberto Posadas’ milestone cycle “Poética del Labyinto” I had to look twice into the CD’s booklet and the score: impossible all these new sounds could happen without any help of live-electronics! Their latest CD sounds simply amazing in every manner! In this PROJECT the “sum” (Sigma) is more than it’s elements. So cool!.
