Abercrombie, bassist Marc Johnson, drummer Peter Erskine, and saxophonist Michael Brecker (on three tracks) turn in immaculate performances, rich in technique and austere, cerebral exchanges, but despite the musical prowess, the listener is left to gaze on blankly, uninvolved. The malaise is typified by Abercrombie's guitar synthesizer, which too frequently renders the leader's brush strokes in a muted monochrome. Similarly, while the signature "Fortress of Solitude" chill of an ECM date is not the issue, the release's enervating engineering does sap the vitality from these performances. There are, nestled among this generally reflective, introverted music, some rewarding bits, notably Abercrombie's short jazz waltz, "Labour Day," where he sets aside the guitar synthesizer and electronic enhancements to serve up some delicious straight-ahead sounds. Two of the tracks with Brecker, Abercrombie's "Sidekicks" and Johnson's "Furs on Ice," have initially engaging melodies and rhythmic interest, but their promise is not realized. These two tracks would make excellent instrumental beds for a pair of latter day Steely Dan songs, but they do not sustain interest on their own. Musicians of the caliber of Abercrombie, Johnson, Erskine, and Brecker cannot fail to generate interest when they get together. This time out, though, their efforts would have been better presented as a master class workshop. The broader fan base, however, can take a pass.
