For guitarists every new Pat Metheny album is a major event, but the shock-haired American has outdone himself with this one. Self-styled “a lush and more orchestrated concept without sacrificing energy, focus and intensity,” it has an epic feel, with scored sections of up to 35 manuscript pages linking dazzling solos by the touring quartet he calls “the slam band”. Joining drummer Antonio Sanchez, bassist Ben Williams and multi-reedman Chris Potter is Giulio Carmassi, an ultra-versatile newcomer who sings, whistles and plays piano, trumpet, trombone, French horn, organ, vibes, cello, flute, clarinet and alto sax. Presumably he charges extra. Mercifully Metheny himself makes no change to his customary cool, high-pitched and slightly woolly sound. Fans should enter “Hammersmith Apollo, Wed June 11” in their diaries.
