Conductor Kwamé Ryan returns to the BSO, introducing the fast-rising Naughton sisters, twins and duo-pianists whom The Philadelphia Inquirer praised as “paired to perfection” after their Philadelphia Orchestra debut. They perform Poulenc’s brilliantly witty Concerto for Two Pianos, portraying a musical game between close friends who just happen to be keyboard virtuosos. The program concludes with Mendelssohn's Symphony No. 5.
