Jeffrey plays the piano throughout, comping in an out way, doing all-over barrages, taking off from motival kernels of musical thought. Lukas Ligeti acts as a free-foil with drumming that can pulsate or go into a-rhythmic zones. And there is the late Luther Thomas on alto--in a Luther-as-post-Bird realm, quoting snatches of Bird-dom, developing melodic motifs that have an out-bop feel to them. The three together enter special places that are pretty rarified.
It was 2007, NYC, and Luther was to live only two more years. This seems to me one of his more important later recordings for all the reasons mentioned. The music is very free and loose and yet there are moments underpinned by structure. There are more musical-structural factors underlining the blowing going on than with the everyday sort of stream-of-consciousness mode. Now of course the stream approach is completely valid and all three players are known for it. It's just that there there are indeed kinds of "Imaginary Control Systems" put into play here.
For all that it makes for a very interesting listen. Get more info on this and other JaZtTapes by going to http://www.janstrom.se/6.-recordings/6.3.-jazt-tapes-6267605
