 His first concert was the Monteverdi Vespers of 1610 in Bath Abbey in April 1990.The choir continues to explore new and unusual works and notably gave a performance of David Fanshawe's African Sanctus and Diana Burrell's Benedicam Dominum, a work which enabled Marcus Sealy to demonstrate the magnificent new Klais organ in Bath Abbey.The choir performed Requiem Aeternam by Jonathan Lloyd in the presence of the composer, which necessitated synchronising with a pre-recorded backing track.
