What is Flamenco?

Since coming across the above video on openculture.com I’ve wondered if a similar exposition of flamenco exists. Brook Zern’s presentation is the best approximation I’ve found so far:

There is little explanation of the music itself though, just a brief demonstration of a bulerias rhythm. Zern is more concerned here with getting across what he sees as unique in flamenco (and bullfighting).
