Lang Lang made a career-changing appearance at Proms 2001 at Royal Albert Hall, playing Rachmaninoff’s Piano Concerto No. 3. Twelve years later—and by then a superstar pianist who sold out two recitals at this 5,000-plus seater hall in just 48 hours—he returned for this captivating solo performance. Three Mozart piano sonatas are played with a light touch and an appealing simplicity, while Chopin’s four Ballades show off his ability to communicate with an audience. And then come eight encores, the pianist egged on by his vast audience. And they hit all the right buttons, with the Ponce and Lecuona high on the list of favorites.
