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.

Get Your Bleep On

If you enjoy the work of Black Dice, autechre, Phoenecia, Eno, or others who build sound waves from scratch with electronic tools, here's a recommendation you aren't likely to get from Pandora or last.fm: pick up a copy of The Csound Book, just for the accompanying CD-ROM. Csound is a standard tool for digital synthesis--essentially a programming language for sound processing--and the book provides an excellent introduction to it. But if you just want to consume sound, not produce it, ignore the book. For a mere $60 you get almost 8 hours of mp3 music from masters of academic computer music and their students. Even if you find only 6 hours to be listenable (not everyone can appreciate pure sine waves), it's a bargain. If you've ever struggled to find computer-generated blurbles that are unpolluted by techno beats but still spicier than new-age ambient, this will be your mother lode. And who knows: if you find Csound itself intriguing and decide to start doing a little experimentation, you may even turn into one of those "laptop musicians" that the real musicians love to hate.
