Frederic Nogray diverts his rock crystal crucibles from their usual function in the silicon industry to generate tactile music, a music that succeeds as much in making the listener's intellect wander as it does in moving the material itself. Although entirely acoustic, this music is powerful, the different-sized bowls being generators of distinct waves operating in the range of frequencies from infra- to ultrasonic. Because of their superimposition and the acoustics of the space they are in, chimeras or interferences are born. A musical event partaking simultaneously in the creation of perception and corporal experience. Digifile.
