A collection chronicling Miles' musical evolution in the studio from 1966-1968 working with his "second great quintet," the latest edition in Columbia / Legacy's acclaimed Miles Davis Bootleg Series provides an unprecedented look into the artist's creative process, drawing on full session reels including all rehearsals, partial and alternate takes, extensive and fascinating studio conversation and more. Celebrating the 50th anniversary of Miles Smiles, the groundbreaking second studio album from the Miles Davis Quintet-Miles Davis (trumpet), Wayne Shorter (tenor saxophone), Herbie Hancock (piano), Ron Carter (bass) and Tony Williams (drums) - this definitive new collection includes the master takes of performances which would appear on the Miles Smiles (1967), Nefertiti (1968) and Water Babies (recorded 1967, released 1976) albums alongside more than two hours worth of previously unreleased studio recordings from original sessions produced by Teo Macero (with the exception of Fall, produced by Howard A. Roberts).
