If you’ve never enjoyed the pleasure of a Lichfield Cathedral Chamber Choir concert, then why not make June the month that you break your duck? With 40-plus years of musicmaking behind them, the 30-plus-member choir is directed by Martyn Rawles, the organist and assistant director of music at the cathedral. The choir’s repertoire covers a broad spectrum, from early music through to more contemporary composers. This latest concert, taking the title O Sing Joyfully, features a programme of sacred music inspired by the cathedral’s currently showing exhibition, Book Of Books.
