Macel li Antune Roca totally pushes the envelope in terms of what I've seen in the world of interactive audio performance.
I read a wonderful long-form dissertation on his work and how it fit with the evolution of performance exploring mechanical additions to the body in an NYU course "Cyborg Culture." It mentioned an early project of Roca's where he set up a surround video/audio environment with an artificial body lying in the center. Visitors could touch different parts of the body and effect the audio-visual scape surrounding them.
It super weird and fresh - overwhelming for the senses.
