On April 9 of this year, the jazz pianist Keith Jarrett sat alone on the stage of an old opera house in Rio de Janeiro, his only company a piano — an American Steinway he described as “not perfect at all.” For nearly two hours, Jarrett played — as he often does — without any idea of what was coming next. It was sheer improvisation. He says the result, now available on the album Rio, was some of the best music he’s ever produced in a career spanning almost 50 years.
