This month the selection varies from sackbutts to serialism, by way of condensed Wagner, Elgar conducted by the much-missed Vernon Handley and music from both Shostakovich and a disciple of his. Among contemporary music there is Osvaldo Golijov’s lively setting of the Passion story and the young German composer Thomas Larcher and the great Henri Dutilleux. There are also more delights from Swiss master Frank Martin. Violin pyrotechnics are supplied by Ysaÿe. But we begin with vintage Gershwin, and that famous looping clarinet.
