From the Royal Albert Hall, London. Presented by Penny Gore. The BBC Symphony Orchestra and pincipal guest conductor David Robertson complete the Proms's survey of Stravinsky's ballets with Agon. It is a dazzling set of 12 dances for as many dancers that the septuagenarian composer based on material taken from a 17th-century dance manual and re-energised using his own unique 20th-century viewpoint. And Stephen Hough completes his Proms one-man piano marathon of Tchaikovsky's concertante works with the curiously neglected Concert Fantasia. Stephen Hough (piano) Steven Isserlis (cello) BBC Symphony Orchestra David Robertson (conductor) Stravinsky: Agon Tchaikovsky: Concert Fantasia in G, Op 56.
