Well, we seem to have a bit of a disagreement below. I hope that I may be able to clarify for those considering this purchase. I am an enthusiastic, if a bit less than fully obsessed, Mahlerite, as well as being a longtime jazzophile. I am also quite skeptical in general of jazz treatments of classical themes; they tend either to be overly reverential (which doesn't prevent their being mediocre) or to simplify the source music (for easier improvisation) to the point where one must question the use of the theme at all. This, to my mind, is an exception. But you must bear that what I like is not always, or even often, what most enthusiasts of jazz OR classical music tend to like. (I'm not inordinately discriminating in my aesthetic judgments, just fussy.) I would venture to suggest that Mahlerians with little interest in jazz would be quite horrified by this recording (as indeed an acquaintance of mine was.) Further, I'd say that fans of contemporary jazz, especially the "downtown" scenesters -- Zorn, Douglas, et al. -- will love this regardless of their taste for classical music. And, as one reviewer noted below, even those who consider Mahler to be an old bloat, but who like challenging jazz, will probably admire this disc. And is Uri Caine one of the most interesting jazz pianists (and arrangers) in decades, or what? His Wagner CD is extraordinary, too, although similar cautions to those cited above (and below) apply.
