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.
