This reissue CD of a live set originally put out on Debut has two very lengthy tracks (the 25-minute “Speak, Brother, Speak” and the 22-and-a-half-minute “A Variation”) featuring solos by tenor saxophonist Clifford Jordan, pianist Mal Waldron, bassist Eddie Khan, and drummer Max Roach (who wrote both of the pieces). The music is somewhere between hard bop and the avant-garde, and the musicians really push each other, although the results are not quite essential. Clifford Jordan fans in particular will find this to be an interesting set. – Scott Yanow
