Guy -
I'm a jazz pianist, too, so I get where you're coming from, and I dig the progressions. My favorite thing about the pieces is how pure the vibes are; they have a singular thing to say, and they say them. This is also my biggest criticism of them. If you didn't know these pieces at all, and someone began playing them from some middle point in the pieces, you wouldn't have an inherent idea of where you were in the piece; no clear "orienting" vibe. "Is this the beginning? Somewhere in the middle?" I would enjoy them more if they had more clear developmental arc. You give away some of that really cool improv stuff too early, I feel. Draw the listener in with some clearer, simpler subjects, and when they're hooked, then swirl them around for a while, and set them back down.
Now, if you goal was to induce that sort of trascendental, almost free-association-like alpha state, I'd say don't change a note. But I suspect you "hear" more in the pieces than most of us do at the first few (several?) listenings?
In any case, great vibe. Solid.
