Sala: St Paul's School: The Wathen Hall, Londres

When one thinks of the ‘X factor’, it’s fairly certain that the first image that comes to mind is not that of a quiet, unassuming man in his mid-sixties, clad in evening dress.

Do you remember when Steve Reich, “America’s greatest living composer”, came to your school concert and you performed his seminal work Clapping Music with the great man? No? Well, Joshua Kellie does. Joshua was one of the talented (and fortunate) St Paul’s School pupils chosen to perform in a concert in honour of the minimalist composer on his 75th birthday.
