Sound Explosions

I'm not sure if these explosions are being caused by the vibrations of the electronic sound, or if there is something else being used to create the powerful eruptions of colored powder. However it's done, it looks fantastic.

Sound Explosions by Martin Klimas 

For Sound Explosions, he asked several musicians to work on short sound sequences, so called patches, using analogue synthesizers made between 1930 and 1990. Klimas shows those synthesizers with all their wires and cables, to give people an idea of the complexity of the sounds he is working with. He then replays the patches on his set, using pigments in place of liquid colors this time. He puts up the volume and lets the colors explode.
