Black Allegheny is a collection of pieces composed using swarm intelligence. Each piece in the album was assembled using custom software that tracks the motion of a virtual herd, and relates that information to pre-selected audio files. This software is called becoming, and it was born from an exploration of Cage's graph and gamut techniques. These techniques were expanded into the domain of digital audio, then swarm algorithms were added.
Available commercially for the first time since its initial 1991 release, Spiegel’s fantastic “intelligent instrument” album testifies to the power of an artist who pushed the boundaries of electronic music to unexplored territory. Bandcamp Album of the Day Jan 11, 2019
