“It is 75 years since the death of Serge Diaghilev, the founder director of the Ballets Russes. Though not himself a dancer, choreographer, musician or designer, Diaghilev had as great an influence on the arts of his time as any primarily creative person. He was a true artistic director, not just an impresario as he is often called. Through his knowledge and ambition, he pushed the frontiers of taste towards a new and untried world.”
