Friggin’ awesome. From the Youtube description:
MooT BooXLe performing on the Synthesizers.com modular analogue synthesizer. This is not a perfect performance, as it was improvised in one go. Also functioning in this video are the Moogerfooger CP-251, the Roland Space Echo, and Reason drums. I was controlling the filter cutoff with a CV pedal. [...] Also, I wasn’t looking at the camera, in case you were wondering. I was watching computer monitors, which were showing visual feedback on what I was playing.
