For an orchestra to lose one anniversary concert may be regarded as unfortunate. To lose two? Welcome to 2020. The City of Birmingham Symphony Orchestra gave its first ever concert on 5 September 1920. But that was only a warm-up, a sort of soft opening if you like. The big public fanfare came two months later, on 10 November 1920, when the all new ensemble descended on Birmingham Town Hall for an inaugural gala conducted by Sir Edward Elgar.
