Part of the BBC Proms. Long a resident of the Orkney Islands, the Master of The Queen's Music, Sir Peter Maxwell Davies, celebrates his 75th birthday today by conducting Mendelssohn's sea-sprayed Hebridean overture and the UK premiere of his own new violin concerto, inspired by traditional Orkney folk and fiddle music. It was written for tonight's soloist, Daniel Hope, and commissioned by Mendelssohn's old orchestra, the Leipzig Gewandhaus, with which they give the work's premiere in August. Proms debutant Garry Walker, the RPO's Permanent Guest Conductor, completes the concert with Sibelius's surging 'swan hymn' symphony. Approx finish time: 20:45. Broadcast Live on BBC Radio 3. There will be an interval.
