From their website: The theatre consists of a foyer, sound labyrinth and main performance space. It is a building within a building, conceived directly for this art form, and built in part with a grant from the National Endowment For The Arts. Listeners sit in concentric circles and are enveloped by speakers in sloping walls, floating floor and a suspended ceiling. Compositions are performed live at each program by a tape performer who directs the sounds through a custom designed console to any combination of the 169 speakers. Sounds are "sculpted" through their movement, direction, speed and intensity on multiple planes in space. Live performance of taped works gives a human, interactive element to AUDIUM's spatial electronic orchestra.
