A PACKED PROM today features four varied - and potentially enthralling - works, including two London premieres for British composers. George Benjamin's Sometime Voices and Robin Holloway's Hymn to the Senses sit either side of the interval, framed by sacred and secular "ecstasies" in the form of Messaien's transcendental L'Ascension and Skryabin's voluptuous The Poem of Ecstasy. Oliver Knussen (right) conducts the BBC Symphony Orchestra.
