The Americas are fine, indeed.
For some strange reason, Coral Rock (issued in the US by Prestige) did not make it out as part of the Free America CD series. Nor did the "Uhuru" track from the Pitchin' Can LP (tho the Cal Massey tune by that name is on the Black Gipsy CD).
Shepp had a fine run for Impulse!, but his work for Fontana, Sonet, and Savoy with both the New York Contemporary Five and Bill Dixon is fantastic. The Dixon-Shepp Quartet on Savoy is a stunner!
Interestingly, the Savoy NYCF date is a "fake" - Shepp and Tchicai are present, and though Cherry showed up to the studio to play his tune "Consequences," Ted Curson did most of the trumpet playing. As Tchicai has discussed, the band dissolved in 1963, prior to the Savoy recording.
