The Classical Jazz Quartet Kenny Barron on piano, Ron Carter on bass, Stefon Harris on vibraphone and marimba, and Lewis Nash on drums seems to begin where the Modern Jazz Quartet of the 1950s left off, right down to the CJQ initials that seem to evoke memories of the earlier group. Bach was the staple of the classical-music treatments the MJQ released.

This special PBS soundtrack includes live recordings filmed at the Newport Jazz Festival for Ron's classic piece SOFT WINDS; a surprise bass duet session at The National Jazz Museum in Harlem with the enigmatic Christian McBride on WILLOW WEEP FOR ME; a session at the Blue Note with guitarist Bill Frisell on MY MAN'S GONE NOW; the first live performance of the two great bassists, Stanley Clarke and Ron playing BAG'S GROOVE, also at the Blue Note; and a joyful version of SWEET LORRAINE featuring Jon Batiste, released here for the first time.

For Robert Altman's Kansas City film, since the story was centered in 1934 Kansas City, Altman wanted to have younger musicians depict top jazz artists of the era playing at one of the legendary jam sessions. He recruited many of today's top modernists and, although they used arrangements based on older recordings, they did not have to necessarily improvise in the style of the time. Actually, it is surprising how close the musicians often come, recapturing not just the music of the period but the adventurous spirit of such immortals as Coleman Hawkins, Ben Webster, and Lester Young. A dozen songs from the film are on this very enjoyable and unique CD, which features such players as trumpeter Nicholas Payton, clarinetist Don Byron, guitarists Russell Malone and Mark Whitfield, pianists Geri Allen and Cyrus Chestnut, altoists Jesse Davis and David "Fathead" Newman, and four of today's great tenors: James Carter, Craig Handy, David Murray, and Joshua Redman. In addition, Kevin Mahogany sings "I Left My Baby." Although there are some audience shouts on a couple of the pieces, this is one soundtrack album that very much stands up on its own.

Sometimes written off as an also-ran to her more famous husband, Alice Coltrane's work of the late '60s and early '70s shows that she was a strong composer and performer in her own right, with a unique ability to impregnate her music with spirituality and gentleness without losing its edges or depth. Ptah, The El Daoud is a truly great album, and listeners who surrender themselves to it emerge on the other side of its 46 minutes transformed. From the purifying catharsis of the first moments of the title track to the last moments of "Mantra," with its disjointed piano dance and passionate ribbons of tenor cast out into the universe, the album resonates with beauty, clarity, and emotion. Coltrane's piano solo on "Turiya and Ramakrishna" is a lush, melancholy, soothing blues, punctuated only by hushed bells and the sandy whisper of Ben Riley's drums and later exchanged for an equally emotive solo by bassist Ron Carter.

The names of Johann Sebastian Bach, Pyotr Ilyich Tchaikovsky and Sergei Rachmaninoff do not necessarily conjure images and sounds of jazz in one's mind, that is until one has listened to recordings by the Classical Jazz Quartet. Although these musicians utilize the same instruments as the Modern Jazz Quartet, they are in no way clones or copycats of that groundbreaking group. They have very much their own sound and style. This is not surprising given the huge talent of the musicians involved; all four are virtuosos on their respective instruments. The themes, although composed in a different time and place, become excellent vehicles for complex, sometimes, bluesy, often swinging and always fresh improvisations in the hands of these musicians.

In an odd bit of programming, Columbia placed the ballads from Miles Davis' February 12, 1964, concert on My Funny Valentine and the uptempo romps on this LP. Davis, probably a bit bored by some of his repertoire and energized by the teenage Tony Williams' drumming, performed many of his standards at an increasingly faster pace as time went on. These versions of "So What," "Walkin'," "Four," "Joshua," "Seven Steps to Heaven," and even "There Is No Greater Love" are remarkably rapid, with the themes quickly thrown out before Davis, George Coleman, and Herbie Hancock take their solos. Highly recommended and rather exciting music, it's one of the last times Davis would be documented playing a full set of standards.

Nefertiti, the fourth album by Miles Davis' second classic quintet, continues the forward motion of Sorcerer, as the group settles into a low-key, exploratory groove, offering music with recognizable themes – but themes that were deliberately dissonant, slightly unsettling even as they burrowed their way into the consciousness. In a sense, this is mood music, since, like on much of Sorcerer, the individual parts mesh in unpredictable ways, creating evocative, floating soundscapes. This music anticipates the free-fall, impressionistic work of In a Silent Way, yet it remains rooted in hard bop, particularly when the tempo is a bit sprightly, as on "Hand Jive." Yet even when the instrumentalists and soloists are placed in the foreground – such as Miles' extended opening solo on "Madness" or Hancock's long solo toward the end of the piece – this never feels like showcases for virtuosity, the way some showboating hard bop can, though each player shines.

Sorcerer, the third album by the second Miles Davis Quintet, is in a sense a transitional album, a quiet, subdued affair that rarely blows hot, choosing to explore cerebral tonal colorings. Even when the tempo picks up, as it does on the title track, there's little of the dense, manic energy on Miles Smiles – this is about subtle shadings, even when the compositions are as memorable as Tony Williams' "Pee Wee" or Herbie Hancock's "Sorcerer." As such, it's a little elusive, since it represents the deepening of the band's music as they choose to explore different territory. The emphasis is as much on complex, interweaving chords and a coolly relaxed sound as it is on sheer improvisation, though each member tears off thoroughly compelling solos. Still, the individual flights aren't placed at the forefront the way they were on the two predecessors – it all merges together, pointing toward the dense soundscapes of Miles' later '60s work.

Bob James' most enduring recording is perhaps one of his least adventurous. Full of simple laid-back melodies, light, airy grooves, and quiet backdrops, it's a smooth jazz "masterpiece." It's an enduring part of his catalog and was the launch pad for many movie and television projects, and for a string of hit recordings for the Warner label in the 1970s, '80s, and '90s. In effect, it insured his financial security for the future. The set is notable for its heavyweight cast including David Sanborn, Ron Carter, Idris Muhammad, Steve Gadd, Eric Gale, Hubert Laws, and Earl Klugh. It also netted the monster hit "Angela (Theme from Taxi)," which continued to get airplay on smooth jazz stations into the 21st century. James is a highly developed pianist, arranger, and composer, and while the music here is as safe as milk, it nonetheless spoke to millions.

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.
