What do you do if you’ve been the superstar of the jazz guitar world for 35 years and have won every award and poll in sight—including a record 17 Grammys? Well, if you’re Pat Metheny, the answer is simple: “and now for something completely different.” His Orchestrion (also the title of his latest CD) is literally a one-man band, a kind of modern “Rube Goldberg player piano,” employing a literal wall of instruments sitting in cages and carpentry, on rods and risers, all triggered from his guitar with the aid of digital technology. There are pianos, vibes, a marimba, drums, guitarbots, mallets—everything but the kitchen sink. And the music Metheny’s written for this contraption, with its shifting tonal center, ranges from post-Coltrane jazz to Brazilian pop, with plenty of room in between for his own solo improvisations. As The New York Times put it, “The Orchestrion is still lunacy, but it breathes.”
