Intermezzo, Garsington Opera, Wormsley, Bucks: Serenely accomplished

Richard Strauss’s Intermezzo may be at one level about a marital tiff, while at another – with words and music written by one of the partners – being a queasy exercise in narcissism. But it’s also a probingly intimate portrait of a marriage, and this is the spirit in which director Bruno Ravella and his cast have approached it.
