Curson is great!
I love the Fontanas especially and his work with Mingus, as well as the aforementioned Futura and the Marge (Cattin' Curson). Certainly, the pianoless quartet stuff he did in the mid-60s is my favorite, but his playing always has a lot of fire.
He's kind of weird, though - very difficult to pigeonhole, for one thing, which is never very good as a selling point. To me, it's perfect inside-outside playing, but there is also a severity to it that might make it less palatable for the boogaloo set. Far more austere than, say Ornette and Don...
