Columbia - 2003 - Four disc box.
April 21-22, 1961 - these live sets are fantastic!

Extremely enjoyable music and superb audio quality, especially for live music.
No matter how much Miles you already have, no matter that you may have all/nearly all of these songs on studio recorded releases, this is a MUST have. This quintet cooks and redefines these songs as their own.
Miles, Hank Mobley (ts), Wynton Kelly (p), Paul Chambers (b), Jimmy Cobb (d).
Extraordinary reissue.
