"Ice is made of water, but it is colder than water. Blue dye comes from the Indigo plant, but when something is repeatedly dyed in it, the color is deeper than the plant itself."
The phrase, greater than the sum of its parts, suggests a thing is better than you would expect from the individual parts, because the way they combine adds a different quality. This principle describes the synergy which exists between individuals working together in a cooperative effort. Collectively, they are able to achieve an outcome superior to individual efforts. Of course this concept is exemplified in music, and sometimes the results defy expectation, explanation, or definition.

And so for one remarkable weekend in autumn in New York, the music was captured and recorded. The music speaks better for itself.
