The City of Birmingham Symphony Orchestra (CBSO) is a British orchestra based in Birmingham, England. The Orchestra's current chief executive, appointed in 1999, is Stephen Maddock. The orchestra's music director designate is Mirga Gražinytė-Tyla. Founded by Neville Chamberlain, the orchestra first rehearsed at 9.30am on 4 September 1920, in the band room at the Birmingham City Police's Steelhouse Lane station. The first public performance, as the City of Birmingham Orchestra occurred later that month, with Appleby Matthews, the orchestra's first chief conductor, at the baton. The programme included Overture: Saul by Granville Bantock, a strong supporter of the orchestra's foundation. However, its official foundation is generally reckoned to have been the "First Symphony Concert" in November 1920, when Edward Elgar conducted a programme of his own music in Birmingham Town Hall.
