My Foolish Heart is an anniversary release celebrating 25 years of the Keith Jarrett,Gary Peacock, and Jack DeJohnette trio's traveling and performing together despite the rich and varied individual careers of its members. Recorded in 2001 at the Montreux Jazz Festival, Jarrett held the tape close to the vest until what he felt was the right time for release -- whatever that means. The bottom line is, listeners are very fortunate to have it. The official live offerings by this group have always been crystalline affairs of deep swinging communication, no matter the material. Not only is My Foolish Heart no exception, it is perhaps the standard by which the others should be judged. Almost two hours in length, the program is comprised entirely of jazz and pop standards -- beginning with a tough, limber, punchy version of Miles Davis' "Four" lasting over nine minutes. That the music begins like this, so utterly strident and swaggering, full of lyric invention and energy, is almost reason enough for purchase. The inherent commitment to the music is not measured: it's total. There are few -- if any -- groups in jazz that have been together for such a long time. And there are few groups new or old that are even capable enough to manage such a wide-ranging selection of the repertoire: from the title track and "Four" to "Oleo," "Straight, No Chaser," and even "Five Brothers"! But the selection of material is only the wrapper. What's inside it is not just the history of jazz but history in the making, because these three prove beyond all measure not only the vitality of the material but also the necessity of the trio interpretation of it, and indeed what is possible: bop, hard bop, post-bop, swing, and here even ragtime, played with all the seriousness and joy it demands. The readings of Fats Waller's "Ain't Misbehavin'" and "Honeysuckle Rose" and Rodgers & Hart's "You Took Advantage of Me" are wild affairs, beautifully executed, sure, but played with the requisite emotion that new interpretations require. ...
