Five IMPRESSIVE Stars! Unity, indeed. Multiple Grammy-winning jazz virtuoso guitarist Pat Metheny has assembled a tight, hard-swinging quartet that sounds like its been working for a long time and he gives the group an impressive array of original compositions. "Unity Band" rides the polyrhythms of drummer Antonio Sanchez (especially "Leaving Town"), anchored by the mellow underpinnings of rising star bassist Ben Williams (great "New Year" solo), and tenor sax luminary Chris Potter who adds his soprano sax and bass clarinet to the mix. Metheny, in addition to the wide palette of his electric and acoustical guitar sounds, adds the program-based Orchestrion EPK instrumentation to the proceedings, as on "Signals (Orchestrion Sketch)".The 'best of the best' begins with the altissimo edginess of the "Roofdogs" unison-theme with hot solos by Metheny and Potter, the avant-garde approach of the tone poem "Signals" with its unusual array of sounds and effects from the Orchestrion EPK and the band, the intensely beautiful ballads "Then and Now" and "This Belongs to You", and perhaps best of all the exotic intensity of "Come and See" which has a great "Willow Weep for Me" Potter quote rising from the musical maelstrom of his solo and a sizzling Metheny improvisation. Pat Metheny is a relentless musical explorer and Unity Band is his impressive new group, producing some exceptional jazz, and it gets My Highest Recommendation.
