(4 stars) Pianist Ben Winkelman's fifth album is so good that, ironically, its overwhelming brilliance may limit its appeal. It is so innovative, and played with such power, that the listener is left open-mouthed. Still, it creates a mystique which I for one find fascinating. Winkelman, imbued with a restless musical intelligence and an impeccable knowledge of the piano keyboard, was born in Oregon, grew up in Melbourne, and has lived in New York since 2010. Recorded in New York Balance features Australian bassist Matt Penman and American drummer Obed Calvaire. Nine compositions are from Winkelman and one from Thelonious Monk. Winkelman is most exploratory in his treatment of time and pulse but, even when the rhythms and time signatures in the music are complicated and ambiguous, three brilliant musicians fly through the music with faultless virtuosity. To take on this album, however, be prepared for a formidable challenge.
