Glyndebourne, the great Sussex opera house, celebrates its 80th anniversary this summer. Hurrah! There is a new music director, too, 31-year-old Robin Ticciati. Hurrah! And he opens the season next week with a new production of Der Rosenkavalier directed by Richard Jones. Hurrah! Summer has begun.

There are few finer plots of land to be on a summer evening in England than Glyndebourne, one of those rare places where the frame matches the picture.
