Unheard works from late composer Sir John Taverner are to be premiered at the BBC Proms to mark what would have been the music maestro's 70th birthday.

Taverner, whose music was featured at Princess Diana's funeral in 1997, died in November (14), but his late works will be heard as part of a tribute, which will also commemorate the 100th anniversary of the start of World War One.

Gnosis and Requiem Fragments will receive their world premieres at the Royal Albert Hall in London during the upcoming Proms season.
