Live, Video: Find classical music concert, opera, ballet and dance reviews | Margaret Leng Tan

While you wouldn’t have guessed from her performance, Margaret Leng Tan did not look happy before she played John Cage’s Four Walls in the Barbican Centre’s Art Gallery this Thursday.

It’s not every day that one goes to a dinner party at lunchtime, but this was a rather special dinner party – A Dinner Party for John Cage. It formed the centerpiece of a lunchtime “happening” at St John’s Smith Square to celebrate the 70th birthday of American-British composer Stephen Montague.
