Where can I read more about the Hemispheres?

If A Brief History of the Hemispheres doesn’t go deep enough, you might want to try one of the following links:

• The paper Alternative Voices for Electronic Sound by Dan Trueman, Curtis Bahn, and Perry Cook, presented at the 2000 International Computer Music Conference, gives a more detailed chronology of the speakers’ development and the rationale for their use.
• SensInstallation, a presentation given by Curtis Bahn and Stephan Moore at the SEAMUS 2002 conference, contains good photo documentation of the first hemispherical speakers, and some information on the first experiments with a 16-channel grid of speakers.
• The development of a specific spherical-speaker-based instrument is detailed in Dan Trueman’s writings about his Bowed Sensor-Speaker Array.
• Learn more about the N-Body project that started it all here.
