Here’s something you don’t see often: jazz musicians not just interpreting the classics but covering a classic album end to end. In listening, one can understand why it is an artist like Marsalis was drawn to an artist like Jarrett: Both provide connective tissue between the harder edge of jazz experimentation and its streamlined, mainstreamed variants; both feel sophisticated without getting too corny; both are hard to pin down when it comes to style. The ballads capture the post-modal/proto-smooth liquidity of a mid-’70s ECM record (“Solstice,” “Belonging”) and the uptempo tracks apply the showiness of fusion over the basic rhythms of early New Orleans (“The Windup,” “‘Long as You Know You’re Living Yours”). The end product is a comment on the nature of tradition: Instead of taking something apart, maybe it’s enough to dust it off and show why it was important to begin with.
