In "Methods Of Expansion And Contraction" disparate scenes and subjects form a continuous montage of contrastive timbres, textures and sonic eruptions, occasionally interrupted by quiet pulses. The work is presented on a 16-channel sound system, the sounds were created on a Buchla Music Easel and Hordijk Blippoo Box.
