Miles Davis' concert of February 12, 1964, was divided into two LPs, with all of the ballads put on My Funny Valentine. These five lengthy tracks (specifically, "All of You," "Stella by Starlight," "All Blues," "I Thought About You," and the title cut) put the emphasis on the lyricism of Davis, along with some strong statements from tenor saxophonist George Coleman and freer moments from the young rhythm section of pianist Herbie Hancock, bassist Ron Carter, and drummer Tony Williams. This hour-long LP complements the up-tempo romps of Four & More.

With the 1968 album Miles in the Sky, Miles Davis explicitly pushed his second great quintet away from conventional jazz, pushing them toward the jazz-rock hybrid that would later become known as fusion. Here, the music is still in its formative stages, and it's a little more earth-bound than you might expect, especially following on the heels of the shape-shifting, elusive Nefertiti. On Miles in the Sky, much of the rhythms are straightforward, picking up on the direct 4/4 beats of rock, and these are illuminated by Herbie Hancock's electric piano – one of the very first sounds on the record, as a matter of fact – and the guest appearance of guitarist George Benson on "Paraphernalia." All of these additions are tangible and identifiable, and they do result in intriguing music, but the form of the music itself is surprisingly direct, playing as extended grooves. This meanders considerable more than Nefertiti, even if it is significantly less elliptical in its form, because it's primarily four long jams.

This is where Miles Davis turned funk into jazz, rock into soul, and chaos into Beauty. With a rotating cast of bands featuring keyboardists Keith Jarrett and Chick Corea, guitarist John McLaughlin, percussionist Airto Moreira, saxophonists Gary Bartz and Wayne Shorter, and myriad other explorers, Davis kept up with the times…and surpassed them. He rocked harder than Sly, got funkier than J.B., and turned jazz inside out, slicing the music open till blood spilled on to the floor. More focused than Bitches Brew, which is all the more surprising since it's actually a piecemeal recording from various dates and venues–some in the studio, some on stage, but all very much l-i-v-e.

After both John Coltrane and Cannonball Adderley left Miles Davis' quintet, he was caught in the web of seeking suitable replacements. It was a period of trial and error for him that nonetheless yielded some legendary recordings (Sketches of Spain, for one). One of those is Someday My Prince Will Come. The lineup is Davis, pianist Wynton Kelly, bassist Paul Chambers, and alternating drummers Jimmy Cobb and Philly Jo Jones. The saxophonist was Hank Mobley on all but two tracks. John Coltrane returns for the title track and "Teo." The set opens with the title, a lilting waltz that nonetheless gets an original treatment here, despite having been recorded by Dave Brubeck. Kelly is in keen form, playing a bit sprightlier than the tempo would allow, and slips flourishes in the high register inside the melody for an "elfin" feel. Davis waxes light and lyrical with his Harmon mute, playing glissando throughout. Mobley plays a strictly journeyman solo, and then Coltrane blows the pack away with a solo so deep inside the harmony it sounds like it's coming from somewhere else.

Recording sessions for tracks that appear on this album took place on May 26, 1958, at Columbia's 30th Street Studio and September 9, 1958, at the Plaza Hotel in New York City. The sessions for tracks on the album in mid-1958, along with the Milestones sessions from earlier that year, were seen by many music writers as elemental in Miles Davis' transition from bebop to the modal style of jazz and were viewed as precursors to his best-known work, Kind of Blue.

This single CD gives one a definitive look at Miles Davis' live show from his last three years. Using funky but unpredictable rhythm sections and leaving space for plenty of solos, Davis created a unique brand of fusion that has yet to be satisfactorily duplicated. Among his more notable sidemen during this era are altoist Kenny Garrett, Foley on lead bass (which he used as a lower-toned guitar), one or two keyboardists chosen from Joey DeFrancesco, Adam Holzman, Robert Irving III, Kei Akagi, and John Beasley, various bassists, drummers, and percussionists, and on "Amandla," the tenor of Rick Margitza. Davis is in consistently strong form throughout the numbers, which include "In a Silent Way," "New Blues," "Human Nature," "Tutu," and "Time After Time." Quite often the live versions of these songs are more creative and exciting than the ones previously issued.
