When one thinks of pairing vibraphonist Gary Burton with another soloist, Chick Corea comes foremost to mind. Burton’s work with guitarist Ralph Towner could hardly be more different, for where the former configuration funnels into a colorful storm of activity, in the latter we find far more intimate gestures articulated in monochrome. Case in point: “Maelstrom,” which starts us on the inside, spinning on its edge like a coin teetering at the promise of rest. Towner is as delicate as ever, fitting his harmonic staircases into Burton’s Escherian architecture with ease. This piece also highlights Towner’s compositional talents, which make up eight of the album’s nine tracks (the only exception being the slice of sonic apple pie that is “Blue In Green”).
