"Good improvisation communicates harmonic progression melodically. Effective melodies manipulate harmonic content through the use of guide tones and preparatory gravity notes, masterfully woven in systematic tension, release, and transparent harmonic definition."
On a serious note, for the jazz enthusiast, our favorite piano trio version has to be the BeatleJazz (Dave Kikoski, Brian Melvin and Charles Fambrough) from over a decade ago. From the other end of the spectrum, there's the Russian Balalaika orchestra for Zdravitsa, some tasty electric mandolin stylings from Jason Anick, and the smooth acoustic sound of the late Butch Baldassari.
