Reissue with latest remastering. Comes with new liner notes. The first of two sets recorded during a weekend in 1961 features the Miles Davis Quintet at a period of time when Hank Mobley was on tenor and the rhythm section was comprised of pianist Wynton Kelly, bassist Paul Chambers, and drummer Jimmy Cobb. What is most remarkable is the way Kelly fits into this particular blend of the Miles band. Kelly's interplay with Chambers is especially brilliant, because his sense of blues phrasing inside counterpoint harmony is edgy and large, with left-hand chords in the middle register rather than sharp right-hand runs to accentuate choruses.
