At the Sonic Zoo

Much electronic music aims to create a sense of navigable sonic space, but that's not the only sort of world-creation available to laptop deities. I'm particularly fond of works that create musical ecosystems populated with alien creatures. Three come to mind in particular. Most recently, there's "Creatures" from Black Dice's "Creature Comforts." But then in the Mesozoic era of electronic music we have the "Forbidden Planet Soundtrack" by Louis and Bebe Barron, and Iannis Xenakis's Gendy compositions. The Barrons' (analog!) work provides both background music and sound effects for the movie -- titles like "Battle with Invisible Monster" and "Nothing Like This Claw Found in Nature" say it all. Xenakis's "Gendy3" is algorithmically generated, so you could argue that it creates a kind of musical artificial life. The timbres themselves are generated on the fly, resulting in a biodiversity that is occasonally painful but always interesting.
