Mariinsky Ballet: Balanchine/Robbins

St Petersburg's mighty Mariinsky Ballet celebrates 50 years since it first performed in London. Of course, back then, they were called the Kirov and they came from Leningrad, but while the names change, the company's proud tradition and superlative technique stays solidly in place. Tonight's programme is a relatively modern one, a triple bill of works by George Balanchine and Jerome Robbins: 'Scotch Symphony', 'In the Night' and 'Ballet Imperial'. Music by Mendelssohn, Chopin and Tchaikovsky accompanies.
