This evening I was part of a capacity audience at Westminster Cathedral for an extraordinary event. Seven Viscount digital organs had been installed, to augment the cathedral’s two famous pipe organs, all in aid of the UK premiere of the late Jean Guillou’s La Rêvolte des Orgues, which formed the last thirty minutes of the evening, and featured leading players from all over Europe. The nine instruments were put to good use in the first hour of the programme in music by Bach and Vivaldi, the percussionist necessary for the Guillou also playing the side drum in Pierre Cochereau’s Boléro sur un thème de Charles Racquet. Frankly, words fail me in attempting to do the event justice, but I would not have missed it — even if I never wish to hear the Guillou again.
