Part of the BBC Proms.From Westminster Bridge and the bells of Big Ben to Bloomsbury Square, in his A London Symphony Vaughan Williams depicts the English capital, where horses still trotted through the streets and the countryside could be glimpsed from Marble Arch. Elgar’s ‘stout and steaky’ picture-postcard scenes of London life join anniversary composer Holst’s Hammersmith, commissioned for the BBC Military Band, in saluting the city. Vaughan Williams’s teacher Stanford (who died 100 years ago) completes the programme, with a selection of reflective songs performed by leading British baritone Christopher Maltman. There will be an interval.
