As good as Miles Davis is on his studio recordings, he never ceases to knock me flat on my back with his live work. This 4 disk set is simply fantastic. This recording has been released with a number of previously unreleased tracks. The sound has also been enhanced. To me, it seemed like Miles Davis was standing in my living room playing. This quintet included Hank Mobley in place of John Coltrane. Hank holds his own and performs quite well on all numbers. You also get the pleasure of hearing one of greatest rhythm sections in jazz – Wynton Kelly on piano, Paul Chambers on bass and Jimmy Cobb on drums. The song “Neo” (also known as “Teo) is true perfection. Buy it and enjoy it. If you're a musician – buy it, enjoy it and take notes.
