"The entire track is created only out of tuned sand tones. No additional sounds or waveforms.
I emphasized the inner notes of the sand grains and mapped them on a sampler as a series of instruments. The grooves are all played live with various techniques, including taping two piezo films to my fingers."
Very cool and interesting experimentation with sand and its sounds factors. Wait a little bit, the tune picks up and is quite fun and light hearted.
