L.A. Decompression 2011 – video
Just a little video clip here demonstrating how people can duet with each other on either side of the van.
We wired the sound so that each side of the van can hear (but not see) the other – making it sonically transparent.
Often, cheapest someone starts riffing on what comes out of the speakers, without being aware that a player on the other side of the van is their partner.
