Some records are designed to provide a peculiar listening experience. You won't listen to Matrix very often (at least not the first CD -- chances are you'll listen to it only once), but you might be glad you did. Disc one contains &Matrix (For Rooms),& a 60-minute piece. The concept is simple: the two stereo channels are completely separated, each one emitting a different frequency. They start in almost-unison and develop on top of each other. These frequencies are designed to fill the listening room with sound waves and the listener is invited to create his own music by moving into the room, especially by shifting the position of his head, changing the balance between frequencies, and thus altering the sound he hears. Simply put: Since the soundwaves overlap differently at any two points of the room, if four people are in the room, each one hears different music. Listening to &Matrix (For Rooms)& with headphones would strip it of any meaning. But it is perfect for tai chi exercises and avant-garde dancers might find something very stimulating here. Disc two contains &.Matrix,& a 31-minute piece. More conventional in the fact that stereo channels are not isolated, this is an avant-garde electronic piece. A light low-frequency pulse gives it structure while pure tones bounce from left to right. Each one of the ten sections is different from the previous: tempos and rhythm structures change, although tone colors remain quite the same. The whole thing feels very dry and the hypnotic stereo games and pure electronic tones can even have a sickening effect on the listener. Matrix is extreme conceptual music, something that is better experienced in a large hall than in your living room, but curious minds might want to try it.
