Heavy metal star turns classical

Durham University grew from one college in 1832

A heavy metal star will premier a major piece of classical music to celebrate a university's birthday.

Jon Lord, who played keyboards for rock band Deep Purple, has written an orchestral piece called Durham Concerto for Durham University.

The university is 175 years old and to mark the event he will perform his piece at Durham Cathedral on Saturday.

Durham is one of the oldest universities in England and grew from one college in 1832 to the current 16.

Based on two sites in Durham City and Stockton-on-Tees, it has 15,000 students, employs 3,000 staff and has an annual turnover of more than £175m.
