Improv on a Grand Central Scale

"For me, the word 'jazz' means, 'I dare you.'" - Jazz legend Wayne Shorter, via NPR

With music, lights and a filmed vantage point faintly reminiscent of the movie Close Encounters of the Third Kind, this improvisation must have caught the passers by at New York City's Grand Central Station off guard. Judging by the looks of many of them, it was an enjoyable experience. 

So how would this possibly relate to the IdeaFestival?

Not knowing what to expect is half the fun, isn't it? And learning to improvise - that's a life long pursuit.
