Part of the BBC Proms. When you place a single, solo instrumentalist in the Royal Albert Hall, a peculiar alchemy occurs. Suddenly the huge space becomes charged with a collective energy, a concentration that amplifies the emotions and gestures of the music performed. When that happens at a Late Night Prom, it's particularly magical. Violinist Alina Ibragimova, making the first of several appearances this season, takes us back to what can seem like the purest expression of music, performing Bach's complete Sonatas and Partitas for solo violin, split across two concerts (see also Prom 21). There will be no interval. Finish time approx 23:30Performers Alina Ibragimova (violin).
