Perhaps the critical difference is the use of an electronic taping in lieu of a second live sextet.
Electronica is good for various things, as can be said of all sound--indeed, of any medium. When it is another excuse for mechanical obedience it tends to bring out the insecurities of players, not their warmest, best human selves. When it provides a framework in which to operate more freely, as it often does, the results can be stirring.
So it was perhaps the players who did not grasp how best to interact with the tape...
I will keep an open mind.
