The English composer Gustav Holst served for many years as director of music at St Paul’s Girls’ School in London, and it was for the pupils there that he wrote his St Paul’s Suite, his most famous work for amateurs and, shortly after, his Brook Green Suite, with its prevailing suggestion of English folk-song. The infrequently performed Concerto for Two Violins and Orchestra begins with a ‘fugal’ scherzo, followed by a very beautiful duet for the two soloists.
