Hope and glory: Birmingham City Organist Thomas Trotter launches the season with a great British celebration. Everyone knows the tune of Elgar’s Pomp and Circumstance March No.1 – and Parry is hardly less stirring. But this “Isle of Noises” has a more spiritual side too, and masterpieces from the English cathedral tradition by Howells and Hurford frame a passacaglia by the composer at the centre of every organist’s life: Johann Sebastian Bach.
