Part of the BBC Proms.In the first of its three Proms this weekend, the Budapest Festival Orchestra and founder-conductor Iván Fischer are joined by celebrated fellow Hungarian Sir András Schiff for one of the great Romantic piano concertos – Schumann’s generous, poetic bravura piece that renegotiates the relationship between soloist and orchestra. Weber’s overture to Der Freischütz sees Romanticism take a supernatural turn when a huntsman makes a deal with the Devil. Darkness and light also meet in Mendelssohn’s atmospheric ‘Scottish’ Symphony, inspired by a twilight visit to the Palace of Holyrood, haunted by memories of Mary, Queen of Scots.
