In the intimate splendour of the Margravial Opera House, Bayreuth Baroque revives Cavalli’s Pompeo Magno with a riot of colors, eight masked countertenors and a Tiepolo-like air of playful chaos.

A landmark in Trafalgar Square, St Martin-in-the-Fields was London’s first free-lending library, is home to one of the world’s foremost chamber ensembles (The Academy of St Martin in the Fields), and puts on hundreds of classical music concerts each year.
