After the innovations of Orchestrion -- in which "computer-operated acoustic instruments" were controlled from Metheny's axe -- he took his mechanized act out on the road, culminating in this double-live set. There's a fuller production sound, but otherwise the performances of Orchestrion's songs don't sound so very different. (Such is the drawback of being as measured a player as Metheny.) The expected rock touches are there, as are the smooth ones. But the guitarist gets a bit wild when playing Ornette Coleman's "Broadway Blues." And Metheny fans should hear both "Improvisations," too.
