When released (2005), a collaborative effort that paired the great pianist and composer with a group of pop and rock stocks from the world over, it was obvious the restless master was entering a new phase of his long career. In that context, makes perfect sense. and his fine band -- (guitar), (soprano and tenor saxophones), (bass), (drums) -- prepare a series of instrumentals and vocal interpretations of the songs of . The vocalists here include those who were inspired by , namely , , and herself on one number (her own recording, , was released on the same day), and some of her peers in the pop world, including and . 's connection to the songwriter is direct in that they are both Canadians and both came up playing clubs and venues in the then new "folk" scene. But understands something implicit about : she was never -- ever -- a folksinger. Her compositions have always walked wildly adventurous rhythmic and harmonic terrain. Indeed, she has played with jazz musicians solidly since the '70s, beginning with the L.A. record, , and toured with jazz groups, including the all-star band assembled for that included ( played on a number of those dates as well). Indeed, when asked no less than to back her on a tour, they had to excuse themselves because they simply couldn't find a way to play behind her. The material here doesn't walk the line between pop and jazz -- something is very comfortable doing. This is a jazz record with vocals. The album's ten tracks are, for the most part, programmed for a vocal tune, followed by an instrumental. This holds true with only one exception in that the disc's first two songs are vocals. First there's the lovely, spooky, smoky "Court and Spark," sung by , followed immediately by the ethereal yet from-the-gut version of "Edith and the Kingpin," sung by (it should be noted here that she is in fine voice, since she hadn't been heard from in quite a while). In this latter cut, it's a testament to the singer, the writer, and , how deeply soulful this performance is. is one of the great soul singers, but this ballad lends itself to another kind of reading and is therefore radically reinterpreted here with 's trademark phrasing, and the restraint doesn't give up an ounce of the emotion in it. The instrumentals begin with "Both Sides Now," which is harmonically rearranged by and indeed feels like it is being played from the inside out. 's meaty yet understated tenor solo is reminiscent of the great tenderness of . It's utterly gorgeous. The shimmering "Sweet Bird" is hiked up a notch and really begins to cook about a third of the way through without losing any of the song's naturally dreamy quality. Again, handles the lyric lines on his tenor with real grace. 's wonderfully large chromatic interplay in both his chords and right-handed lines from the middle register are achingly beautiful. The final two instrumentals on the set are surprises, but they are placed here, perhaps, because they were inspirational to . The first is a fine reading of the / tune "Solitude," a sweet, tender ballad that nonetheless contains some unusual moments in its drifting structure and in its changes. The latter is 's classic "Nefertiti," written while both he and were with in the second quintet. It didn't sound like this then, but that's the beauty of 's best work: it can be revisioned a hundred times over in so many different ways yet is unmistakably his. The other vocal performances here are basically stellar. 's version of the title cut offers a completely different dimension of her voice. The soul feel is still there -- and she pushes it into the grooves of the tune. But her clipping of her lines at the end, making them so clean -- especially in the way they interact with 's soprano -- is rather stunning. The hinge of the set is 's performance of a song she wrote with (who co-produced the album with and has been 's producer for ages). Her voice has lowered a bit after a lifetime of cigarette smoking and age, but she's lost none of her power. Her unique phrasing and ever-shifting rhythmic invention brings the listener back to why exactly this recording makes so much sense! She is a jazz singer and always has been. This band lends even more weight to that argument. The nearly seductive interplay between 's and 's six-string fills and her voice is almost erotic. 's "Amelia" is, while hauntingly gorgeous, the most outside performance on the record. Her voice is closest in some ways to 's own in timbre, but her way of holding syllables until they melt into the ones that follow adds space and texture to the band's accompaniment. She is one of them, not in front of them. Finally, of course, there is , the only male vocalist on this collection. He doesn't even try to sing. Instead, accompanied only by , he recites "The Jungle Line" as poetry. Perhaps because is a poet as well as a songwriter, he is able to offer a completely new interpretation out of the tune. He allows the words to represent themselves, plaintively reading them as improvises the melody line, in a modal frame and in a startling array of minor key permutations. approaches brilliance; it's another accomplishment in a career full of them for . The album doesn't simply recontextualize . Any fan of hers has known that she never comfortably fit the whole singer/songwriter thing anyway. It actually does that more for jazz and pop. He takes a sound that has been floating around since issued her debut album, and roots it deeply in the jazz camp without giving up the immediacy of sophisticated adult pop -- which is, in a way, an element of the tradition of jazz itself. For jazz fans, this is a wonderful new chapter, a new way to hear him (and ). For pop and fans, this is a way to step quietly into another world and experience wonders. This CD was nominated for a Grammy award in 2007 for Best Album, Best Contemporary Jazz Album, and 's improvisation on "Both Sides Now" was also nominated for Best Jazz Instrumental Solo.
