Computer music pioneer Nicolas Collins's 1974 generative music piece Pea Soup has been rewritten as a piece of open access software. The original Pea Soup creates a feedback network of mics and speakers that tunes itself to the acoustics of a space and responds to other waveforms and objects in the room.
The open access version, Pea Soup To Go, was made available this week on the 40th anniversary of its first performance. It is constructed from over 70 recordings of the piece in a variety of different spaces made by Collins (author of Handmade Electronic Music – The Art of Hardware Hacking), including concert halls and caves. The site autoplays audio and crossfades between different versions of the piece, resulting in an endless, slowly modulating mix.
