Violist Philip Dukes is celebrating the 20th anniversary of his first recital at London's Purcell Room by returning there to perform on 20 March, and he will be playing on a special instrument – the 'Archinto' Stradivari of 1696.

One of the few surviving Stradivari violas, the 'Archinto' has been in the collection of the Royal Academy of Music in London since 1890, and is only allowed out for performances a handful of times a year. It is, however, enjoying an unusually busy few weeks, having been used by the Piatti Quartet in a recital at the Ashmolean Museum in Oxford on 4 March.
