Just got back from watching Dave Liebman play at a concert at the U., and I was struck by the degree to which he infected everyone onstage with him and in the audience with his energy and vibe. For the players, he raised them up to a higher level, and they all played above their heads with an energy I don't usually see from them (even though they're all great players). The room was more alive than I've seen it in years, and the intensity was thick enough to cut with a knife. From the audience perspective, you could feel the energy coming off the stage in waves, and it was like being transported to a different place for a little while. I started thinking about other players I've seen who seem to have the ability to color an entire room and its occupants with their own vibe and transport them to that place (each in their own way, of course): Chick Corea, Frank Morgan, Fred Hersch, and Kenny Barron come to mind as players I've seen recently who have done this. All seem to be conduits for something much purer and greater than simply soundwaves, and I am astounded each time I see and feel this happen. Another thing about the phenomenon is that the energy they put out seems to stay with you for awhile after the music has stopped, so that if you go play immediately afterwards, you still feel the heat of it. After a while, it seems to dissipate, and you are back to being just plain old you again. Just thought I'd throw the subject out there and see if anyone wanted to relate any similar experiences, or thoughts on what this "contagious energy" really is.
