that capacity for a wide range of concert and recording projects with conductors such as Sir Colin Davis, Claudio Abbado, Lorin Maazel and Christoph von Dohnányi. With Seiji Ozawa he collaborated in performances of Olivier Messiaen's opera St Francis of Assisi in London and Berlin, and with Andrew Davis in performances of Sir Michael Tippett's Mask of Time, the recording of which has been critically acclaimed. Stephen Jackson The Chorus was directed from 1989 to 2015 by Stephen Jackson. In his time, he prepared a huge repertoire for more than fifty maestri, including Bernard Haitink, Pierre Boulez, Simon Rattle and Roger Norrington, and composer-conductors such as Luciano Berio and John Adams. Jackson regularly conducted the BBC Symphony Chorus himself, in the concert hall, on tour and in the recording studio. He particularly extended the range of the ensemble's large-scale a cappella choral repertoire, including Rachmaninov's Vespers (All-Night Vigil), Schoenberg's Friede auf Erden and Poulenc's Figure humaine; recorded works by Carl Rütti and Judith Bingham; and commissioned works by Richard Rodney Bennett, Mark-Anthony Turnage and Stephen Montague. The BBC Symphony Chorus celebrated its 75th anniversary in 2003 with a number of concerts in London, and a week of special broadcasts of its most memorable performances of recent years as part of BBC Radio 3's Afternoon Performance (17-21 November 2003) presented by Tommy Pearson.
