Justin, I'm in the same boat as you. I've never seen Solal in person, and I likely never will. I understand that he's already semi-retired. He's one of my favorites -- so it's a bit of a bummer. ... I'm grateful for the recordings, at least.
I will admit that I much prefer Solal's solo and small combo recordings to his large ensemble work. I have the Carlyne LP that you posted above (and others, like his Dodecaband Plays Ellington disc for Dreyfus), but they've never given me the electric jolt that his piano playing does. Just my personal response, of course.
Now giving this another spin:
Another one of Kloss' LPs from the Seventies that deserves to be reissued -- and likely never will be.
"Dancers in Love"!
