A highly distinguished pianist and the first classical performer to be granted a MacArthur Fellowship, Sir Stephen Hough’s magic is best experienced live — in these concerts, he performs Mozart’s Piano Concerto No. 21, which begins cautiously but soon dives into its true warmth and urgency. Guest conductor Jean-Marie Zeitouni guides this rollicking dance across central and eastern Europe: hear the spirit of Ligeti’s Romania, Kodály’s love for his native Hungary, and Mozart’s musical postcard from Prague.
