Release (2002/2008)

Compensating-system tuba


Release, the second piece on the solo album States of Rushing, draws on the ‘noise-valve’ technique to filter the air made turbulent by the rotated piston valve. The initial time structure is repeated twice, and upon each repetition an extra layer of material is added. The result could be viewed as an acoustic version of tape overdubbing.
