Produced with loving care by Claude Nobs, founder of the Montreux Jazz Festival, with no edits or overdubs, this document of Miles Davis's Montreux performances shows through never-before-released material how Miles and company transformed his music live, with their fire, invention, and interplay. The list of sidemen on these dates is a who's who of today's superstars, including saxophonist Dave Liebman, guitarists John Scofield and Robben Ford, keyboardists Adam Holzman and Kei Akagi, bassist Michael Henderson, and percussionist Mtume. Most of the music on these discs features versions of Davis's fusion "hits." The funky and R&B-ish ditty "Ife" and the bouncy "Calypso Frelimo" are rendered with more gusto than their studio versions, as are the in-the-pocket, mid-'80s tunes "Star People" and "New Blues." A package this big has more than a few surprises, however. Chaka Khan lends her powerful pipes to Davis's unique cover of the Michael Jackson sleeper, "Human Nature," and "Al Jarreau" is an upbeat (though too short) tribute to the great vocalise master.
