A trio recording in this case featuring Charlie Mingus on bass and Max Roach on drums. Recorded in Sept., 1962. Ellington alone emphasizes the beautiful melodies of the classic ballads "Solitude" and "Warm Valley," but the edge returns when the rhythm section joins him. Mingus, who actually idolized Ellington, seems to be purposely agitating the master, almost taunting him. You'd say the synergy was magical, except that they seem to be working against each other.
