Roger Wright’s reign as director of the BBC Proms has luckily spared us some of the more desperate themed programming that ran through the seasons in Nicholas Kenyon’s day. "Music and Shakespeare", I remember; music and the sea; and one year of Spain, Spain and Spain. I never wanted to hear another castanet again. But individual concerts still need careful planning. And if you’re hunting for a convenient hook, the name of Serge Koussevitzky – fiery Russian conductor of the Boston Symphony Orchestra for 25 years, double-bass player, minor composer, famed promoter of the new – is as plausible a hook as any. Also, this is his anniversary year: he died in June, 1951.
