In 1960 bassist Charles Mingus helped to organize an alternative Newport Jazz Festival in protest of Newport's conservative and increasingly commercial booking policy. The music on this LP (which has been reissued on CD) features some of the musicians who participated in Mingus's worthy if short-lived venture. Trumpeter Roy Eldridge performs three numbers with pianist Tommy Flanagan, Mingus and drummer Jo Jones; of greatest interest is "Mysterious Blues" for it adds trombonist Jimmy Knepper and the unique altoist Eric Dolphy successfully to the group. The other selections match up drummers Max Roach and Jo Jones with Roach's quintet (featuring trumpeter Booker Little) on "Cliff Walk" and feature singer Abbey Lincoln on "Tain't Nobody's Bizness If I Do."
