Singer and broadcaster Clare Teal transports us back to the 1930s, as two of the greatest swing bands of the day – one led by Count Basie, the other by Duke Ellington – faced off in a memorable Battle of the Bands. In this Late Night Prom, present-day leaders James Pearson and Grant Windsor fight it out in their own, roof-raising battle.

The BBC Proms welcomes back Canadian violinist James Ehnes as soloist in Walton’s virtuosic yet intimate Violin Concerto. Søndergård and the BBC NOW continue with a suite from Sir Peter Maxwell Davies’s ballet Caroline Mathilde and two great orchestral works by Sibelius – his soaring Fifth Symphony and the more delicate, mystical Swan of Tuonela.

Baritone Roderick Williams joins the BBC Scottish Symphony Orchestra in music inspired by the First World War. Butterworth’s setting from Housman’s A Shropshire Lad depicts a world on the brink of collapse, while Vaughan Williams’s Pastoral Symphony is a curdled vision of war-ravaged France. Both Rudi Stephan and Frederick Kelly were killed in the conflict, the latter leaving behind the exquisite Elegy for strings, the former the more muscular Music for Orchestra (1912).

Celebrating its 50th anniversary this year, the Monteverdi Choir returns to the Proms under Sir John Eliot Gardiner for one of the greatest choral works of the repertoire – Beethoven’s mighty Missa solemnis. Join them on this tumultuous spiritual journey in music that defies simple resolution.
