One of the fastest-rising stars in classical music today, Finnish conductor Tarmo Peltokoski has recently been named Principal Guest Conductor of the Rotterdam Philharmonic and Deutsche Kammerphilharmonie Bremen, Music and Artistic Director of the Latvian National Symphony Orchestra, and Music Director of the excellent Orchestre National du Capitole de Toulouse—who join him here for their first showing together at the storied Royal Concertgebouw in Amsterdam!
