Following their recent performances of Haydn's Nelson Mass, the Royal Philharmonic Orchestra and City of London Choir collaborate on the Cadogan Hall stage once again, this time in Haydn's Theresienmesse for an evening of choral and classical treats. The concert opens with the delicacies of Mozart’s short sacred work, Tantum Ergo, next Leon McCawley takes centre stage for Mozart’s Piano Concerto No.24. Beginning quietly but menacingly, the broadly spanned first movement stands a world apart from the beautiful second movement with its charm and pure tranquillity, before Mozart returns to the tragic mood of the opening movement in a whirlwind finale. Haydn’s Mass in B flat major (Theresienmesse), complete with marked musical contrasts, closes this spring concert with the vitality of unfailing inspiration so characteristic of this remarkable composer. No under 5s.
