 The Bath Bach Choir's biggest recent challenge – supported by the combined forces of Exeter Festival Chorus and The Wellensian Consort– was arguably staging two performances of The Saint John Passion, an exceptionally demanding contemporary piece composed by Sir James MacMillan CBE and sung in his presence.Performances took place at Wells Cathedral and then Exeter Cathedral in March 2013, with soloist Mark Stone as Christus, and Alexander Hohenthal leading Southern Sinfonia.The baroque performance of the Messiah (Handel), accompanied by Music for Awhile, with Leader Margaret Faultless, a musician within the Orchestra of the Age of Enlightenment went down especially well with the packed audience.
