I did this unedited free improv on my six foot Kawai grand piano on November 8, 2011 and the spring video shot of the Boulder Creek Path with a 42x optical lens on May 22, 2013. I like how the random walkers and biker move with the music even though I did not plan either to do that. It is how our minds work to find patterns and put things together. It is best seen in HD on a full screen.
