Recording of Włodzimierz Kotoński's Microstructures. This piece utilizes sections of fragmented tape to create a montage of sound layers in very dense structures. The composer used the sound of knocking on wood, metal, and glass to form a new sound material and spatialization of sound. These sounds recorded on magnetic tape were cut, melted, and glued randomly into random sequences from which loops of different length were formed and copied onto a layer which finally resulted in this desirable microstructure.

Painting of black and white contrasted polka-dots that appear to vibrate and form three-dimensional depression at the center of the piece. In this and other early works, Riley "wanted the space between the picture plane and the spectator to be active." She later explored color contrast.

Recording of Lucien Goethals Cadenza. This composition is part of a work for orchestra and electroacoustic music. It is a solo for tape recorder, placed in the middle of the work. The basic material is electronic sounds and concert sounds (instrumental sounds). The overall shape is the result of superimposing a large number of fairly simple sound layers.
