Vitaly Vatulya - soprano saxophone Olivier Sliepen - alto saxophone Bas Apswoude - tenor saxophone Harry Cherrin - baritone saxophone Chameleonic and passionate, that would be the best way to describe the four saxophonists that make up the Amstel Quartet. Whether it is old music or the very latest sounds, pop music, jazz, classical or world music – once you hear the Amstel Quartet play, all borders between these genres simply fade away. Technical limitations appear non-existent and musical boundaries are there merely to be crossed.
