Part of the BBC Proms.Celebrating its 20th anniversary this year, François-Xavier Roth’s award-winning orchestra Les Siècles presents music from sonic pioneer György Ligeti alongside two late works by Mozart – pieces separated by two centuries, but united by the spirit of revolution. Unperformed until 1971, Ligeti’s vibrant Concert Românesc (‘Romanian Concerto’) is a light-footed celebration of Romanian folk music – real and invented. His Violin Concerto – performed here with German soloist Isabelle Faust – is one of the most original of any age, while Mozart’s final symphony, the ‘Jupiter’, with its astonishing finale, is the last word on the genre from a master innovator. Russian pianist Alexander Melnikov is the soloist in Mozart’s Piano Concerto No. 23.
