I guess this clip is predictably awesome. I don't care what these four musicians are playing, if they are playing together it is going to be special. Even 'Hush Little Baby'! As people who are at the absolute top of their profession, all four of these guys are used to being the center of musical attention. Yet in this clip, each one is both contributing and not even remotely over-stepping their role within the ensemble. This is unheralded yet imperative quality in any musician.
This is such a simple version of an incredibly simple tune yet there is something very special about it. Oh to have been in the audience for this performance.
