The Expanding Universe

Laurie Spiegel The Expanding Universe (1983) Composto em 1974-76 com um computador a tocar os vários sons controlado por um equipamento de síntese analógico com recurso ao sistema híbrido GROOVE (Generating Realtime Operations On Voltage-controlled Equipment) desenvolvido por Max Matthews e F.R. Moore no Bell Labs. A interacção com o computador era feita através de um teclado, uma prancha digitalizadora, botões e interruptores, e também com um complexo "algoritmo" escrito em FORTRAN. 01: Patchwork; 02: Old Wave; 03: Pentachrome; 04: The Expanding Universe

Drums

Laurie Spiegel música do álbum The Capriccio Series Of New American Music Number Two (1983) Peça criada em 1975 com o sistema GROOVE no Bell Labs. "A technical breakdown of the GROOVE setup can become pretty complex, but, in brief, the system was controlled from a room that held a console, a monitor, a three-octave keyboard, and a joystick operated by the user, all of which was separated by a glass window from a temperature-controlled room with a large DDP-224 computer, which was in turn linked up to a digital magnetic tape drive down the hall. (...) The extent of Spiegel’s venturesome spirit as a composer is further revealed on the reissue (of The Expanding Universe). In particular, her programming of pitched percussive accents on the polyrhythmic track “Drums,” as well as on the five-minute “Clockworks,” looks ahead to the not-yet-invented world of minimal techno."
