Man, I love what your doing here, really inspired.
I personally have been studying this kind of thing; neuroaccustical stimulation, for some time now. I've experimented with using Delta frequency stimuli as a treatment for insomnia. For those who don't know, Delta frequency is the slowest of the four brainwave frequencies, the brain produces these when it's in its deepest stage of the resting cycle.
It's intersting to see someone trying to apply this concept to parkour. You'll have to explain the connection though, how does the video utilise this like you where saying?
The beat was a great endeavor, although, I'll admit it, could be taken allot further using more sounds and more frequent patterns, you know layering more together, you could have a whole rhythmic symphony going here.
The video style was really cool to, this is the kind of thing we need more of; people taking an real experimental artistic angle to parkour filming.
Nice
