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.

THE LONDON-BASED Sinfonia 21 pays a visit to the Dartington Festival in their largish chamber orchestra variation. They play sextets by Martinu and Poulenc, the Australian Peter Sculthorpe's Night Songs, plus a major Viennese classic - Schubert's majestic Octet.
