About the music:
from Director/Producer Michael Mahonon
The majority of the soundtrack is music composed by Falun Gong practitioners inspired by their practice of Falun Gong. The music originally had been posted on the internet before Sandstorm was even conceived for any who may be interested in listening. It was donated anonymously to the project for use in the film.
I chose a number of these pieces and cut sections, rearranged them and layered at certain times. Working with Corban Hu, the sound editor, we timed and matched the music to the edited scenes. On several occasions, I suggested that we begin to play one of the pre-recorded pieces at a particular spot in the visual edit and just let it play along with the video, to see how well it would sync and how much we would have to alter. Several times, the pieces fit into long segments of the film as though they had been specifically composed to match the edited scenes. Changes of pace and rhythm, and accents in the music would often happen at the exact moment of visual cuts in the film, leaving us amazed as we watched the music matching up to the edited film as though it had been intentionally created for those scenes. One piece matches perfectly for more than a four minute stretch and another for over two minutes, even crossing over into several different scenes while maintaining the sync.
