Query: Best vibraphone cd I have.

This is a tremendous cd all around but in particular I would like to emphasize the work of vibraphonist, David Friedman. This instrument is one that I enjoy but not one of my favorites but on this cd it is fantantic, probably the best that I've heard. Of course, the work of the rhythm section (and its production on the cd) are also fantastic. Finally, there is wonderful playing on trumpet and flugelhorn by Marvin Stamm. One of the 2 or 3 best cds I've bought this year.
