Denzler (tenor sax) and Koch (bass clarinet, soprano sax) blow their way through four pieces all entitled Asymetries. Both are exponents of the Swiss impro scene. Denzler is a player from Geneva (Switzerland). His cooperations are to numerous to mention them all. All in the field of improvised music. He is for instance member of Hubbub an improvisational collective. Koch is known for his work with celloplayer Martin Schutz. Denzler and Koch met in 1996 at one of Butch Morris ‘Conductions’ workshops. Since 1999 they established themselves as a duo. With this cd they make their debute on cd. It’s instantly clear that both players are not satisfied with the conventional playing of these instruments. They use different kinds of technique in order explore and expand the spectrum of sounds that can come from these instruments. They do not use electronics, all is done by mouth and fingers. All this done not just for the sake of discovering more technical possibilities, or to add some more pages to the catalogue of sounds. They are means in a musical process that aims at communication. Denzler and Koch give room to each other, letting the other act or react. The result is a set of well balanced duets. The CD starts with very soft sounds. Short lines and figures come from and disappear into silence. Overall the music is contemplative, concentrated and controlled. It switches from soft and subtile to jerky and growling. For some reason I compare their music with Schwitters’ Ursonate. Something completely different, be sure of that. But on the other hand both could be described as examples of soundpoetry that stay close to breath.
