For connoisseurs of modern jazz guitar, “Conversation” will be a revelation. The interplay between the two guitarists Pat Martino and Michael Sagmeister is marked by profound mutual understanding - which is no small wonder, considering Michael Sagmeister has long been interested in Martino’s music. In the meantime, these two world-class musicians are connected by a personal friendship, and they now communicate as two equals. Joining them are Michael Sagmeister’s long-standing rhythm group, Michael Küttner on drums, Thomas Heidepriem on bass. The powerful and flowing grooves of the two musicians form the basis for the unfolding of well-set lines and improvisations by Martino and Sagmeister. The tradition of modern jazz guitar can be followed in exemplary form on “Conversation”, and at the same time, one can hear how a guitar duo should sound in our time.

Guitarist Kenny Burrell leads a strong jam session that features the talented but very underrated trumpeter Louis Smith (who sounds a bit like Lee Morgan), the similar but contrasting tenors of Junior Cook and Tina Brooks, pianist Duke Jordan, bassist Sam Jones, and drummer Art Blakey. Jordan's tongue-in-cheek "Scotch Blues" is a high point.

The second of two CD reissues of a jam session led by guitarist Kenny Burrell features the talented if forgotten trumpeter Louis Smith, both Junior Cook and Tina Brooks on tenors, pianist Bobby Timmons (Duke Jordan was on the first volume), bassist Sam Jones and drummer Art Blakey. The all-star group performs two standards ("Caravan" and the guitarist's feature on "Autumn in New York"), Sam Jones's "Chuckin'" and Burrell's "Rock Salt." This is excellent music that easily fits into the bop mainstream of the period.

If you're an air guitarist, Al di Meola has likely been your man since his days as an unknown 21-year-old addition to Chick Corea's Return to Forever in the mid-'70s. Over the years since leaving RTF, he has been afforded the opportunity to record regularly, and this CD represents a good overview of his discography, primarily for the Columbia family of labels. His early dates Land of the Midnight Sun, Elegant Gypsy, and Casino are well represented, in addition to his collaborations with Jan Hammer on Tour de Force: Live. His middle-period efforts are not all that vital, as repeat ideas and predictable flash lost their original value even to the staunchest fans, therefore making this collection less than essential.

The success of Weekend in L.A. no doubt prompted producer Tommy LiPuma and Warner Bros. to give George Benson another double album (now on one CD) – and this, like its three Warner predecessors, also went Top Ten. It is also, alas, slicker, more romantic in mood, and more bound by perceptions of formula than the others, fussed over in three different studios in earnest search of another hit single (the dance-tempo cover of L.T.D.'s "Love Ballad"). Most of the touring band, including Ronnie Foster, Ralph MacDonald and Phil Upchurch, is back, and Claus Ogerman's soft symphonic touch provides most of the backdrops, with Mike Mainieri supplying the orchestra on three tracks. Even at this point, the great guitarist is still given much room to burn – the balance between instrumentals and vocals remains close – and Benson comes up with some tasty stuff when the rhythm section pushes him on "Nassau Day" and "You're Never Too Far from Me." Ultimately there is just enough jazz content amid the velvet soul to keep guitar buffs interested.

The R&B elements get stronger, the sound and mix are more attuned to the dancefloor, yet this brings out the best in George Benson's funky side. Thanks in part to the more rigid beat, Benson pares down his style to its rhythmic essentials, refusing to spray notes all over the place at random, and as a result, the record cooks and dances. His treatment of Vince Guaraldi's "Cast Your Fate to the Wind," hugely complemented by Joe Farrell's wistfully prancing flute, is a mini-masterpiece in the use of space, of hitting exactly the right stabbing note right in the pocket. Again, Creed Taylor turns to a James Brown alumnus, David Matthews, for arrangements, and he discreetly and wisely stays out of Bad George's way. Buy this one for "Cast Your Fate," but there is plenty more to savor here.

A well-rounded exploration of every shade of blues Ford does so well: Chicago-style ("When I Leave Here"), jump blues ("The Miller's Son"), jazz-blues balladry ("Don't Let Me Be Misunderstood"), and Texas shuffle ("Tired of Talkin'"). Ford's buttery lines and burnished tone (and his boyish voice) are captured in all their glory by producer Danny Kortchmar. Solidly anchored by bassist Roscoe Beck and drummer Tom Brechtlein, Ford solos liberally, taking the fast funk of "Think Twice" over the top with a burning series of rapid-fire runs and well-tooled turnarounds. Slowing down for a languid version of Willie Dixon's "I Just Want to Make Love to You," Ford plays it raw and soulful, recalling B.B. King. He then turns up the pace on "Strong Will to Live," closing out the album with a signature solo full of fire and drama.

The talented guitarist Joe Diorio has mostly recorded for obscure record companies throughout his career including this set for the completely forgotten Zdenek label. The early-'80s LP features Diorio (who has always had his own sound) in a trio/quartet with other Los Angeles-based musicians: keyboardist Carl Schroeder, bassist Bob Magnusson and drummer Jim Plank. Diorio stretches out on five standards (including Jobim's "Bonita") plus one of his originals, playing some fine post-bop guitar that is often strikingly original.

Though he has shown a mastery and affinity for both electric and acoustic axes, Tommy Emmanuel's Higher Octave debut, Midnight Drive, finds him focusing almost exclusively on warm yet frequently aggressive acoustic melodies, complemented here and there by the raw, plugged-in energy of Robben Ford and Larry Carlton. The overall mix is the kind that smooth jazz lovers find easy to swallow, but offers more bite and adventure than most like-minded releases in the genre. Smooth jazz radio may find an easy mark with a laid-back take of Sting's "Fields of Gold," but Emmanuel's other tracks dig deeper, showing off a stylistic chameleon drawing from the many phases of his career. His soft pop side comes out on power ballads "No More Goodbyes" and "Stay Close to Me," the latter reminding us why guest saxman Warren Hill's biggest hit to date was called "The Passion Theme." Emmanuel's more aggressive blues-rock side (honed no doubt by a few years in the progressive mid-'80s ensemble Dragon) emerges with Carlton's help on "Can't Get Enough." The striking contrast between the pastoral, folksy roads of "Drivetime" and the disc's best track, "Villa de Martin" best reflects the gamut of Emmanuel's approaches.

This album is something of a legend in the annals of ECM lore, as it was the only ever recorded by the fantastically talented Steve Eliovson. With Collin Walcott on percussion for support, the since unheard-from guitarist carves lasting impressions that can now be thankfully heard on CD. The experience begins in “Venice” (as in California), where the guitar speaks with tabla like two continents connected by tectonic plates beneath an ocean. Eliovson’s sonorities are pristine, especially in “Earth End” and in “Slow Jazz,” where the precision of finger placement and the occasional bent note add a soulful turn of phrase. The album’s portal is “Awakening,” a submarine communion of gongs that closes one door while opening another. The title track is buoyed by a glimmering triangle and arpeggios from an internal guitar, while the external speaks in tongues with the various percussive accents that flit in and out of its view.

This is the debut long-player from Leon Redbone (guitar/harmonica/vocals/throat tromnet), a one-man folk/jazz enigma. Although it was incorrectly rumored that the artist was a musical visage of Frank Zappa, Redbone began getting notice during a stint in Toronto, Ontario, in the early '70s. For On the Track (1975), he offers a uniquely authentic revival of turn-of-the-century melodies, including those of the Singin' Brakeman, Mississippi Blue Yodeler Jimmie Rodgers ("Desert Blues") as well as Fats Waller ("Ain't Misbehavin'"). However, he liberally applies the same notable technique to a wide array of pop standards from the likes of Irving Berlin ("Marie") and Johnny Mercer ("Lazy Bones"). The minimalism in the arrangements provides an understated delivery focusing on Redbone's distinguished baritone vocals. This includes his self-proclaimed "throat tromnet" – an orally generated device that sounds like a combination trombone and trumpet. Accompanying him are quite an aggregate of studio stalwarts – such as percussionists Ralph McDonald (castanets) and Steven Gadd (drums) as well as legendary jazz heavies Milt Hinton (bass), Garnett Brown (trombone), Seldon Powell (sax), and Jonathan Dorn (tuba).

Jim Hall is no stranger to guitar/bass duets after several memorable outings with the likes of Ron Carter and Red Mitchell, but this series of studio sessions is even more challenging, mixing it up in pairings with Dave Holland, Christian McBride, Charlie Haden, George Mraz, and Scott Colley. Only three of the 13 pieces are standards, including a soft and sparse treatment of "All the Things You Are" with Mraz, a whisper-soft and slowly savored "Don't Explain" with Haden, and a switch to acoustic guitar for a tense "Besame Mucho" with Colley. Hall's skills as a composer are vastly underrated by the jazz audience as a whole, but his fellow players recognize his formidable skills. He makes a relatively rare appearance on a 12-string acoustic guitar in his challenging opener, "End the Beguine," in which he and Holland rise to the demands of this captivating piece…
