The beauty of the sound: clear, transparent, precise, a work of art - and that includes both the actual recording, and the subsequent production - something that was already an essential difference in clarinettist, composer and sound researcher, Rolf Khn's musical concept. The pieces were recorded on separate sound tracks, in a stereo technique that lends a visual sense to the music. In fact, there is a cinematic feel as sounds project on the mind's eye. For this special, sensual production, Khn has gathered his Berlin trio around him - his "working band" with Christian Lillinger (drums), Ronny Graupe (guitar) and Johannes Fink (bass).

Their previous studio recordings have had a sense of freedom about them that has indicated the direction in which these musicians are heading. Theirs is a concentrated, compact play that has moved further and further away from the delineation between notated and improvised music. Duo and group improvisations flow across the interstices between the sketched-out musical islands. On 'Stereo' Rolf Khn goes even one step further; he condenses the compositions, providing accurate and concise sound ideas. The sound of 'Stereo' is reminiscent of the Blue Note aesthetics of the 1960s, when the stereo sound was something outrageously new and greatly enhanced the tonal possibilities of the recordings.
