There is no finer performance of the Elgar First Sonata than Kynaston's at Ingolstadt (Mitra OSM 16157), on vinyl from 1977. The Elgar Sonata is not organ music, but music played on the organ. (The Second Sonata is Brass Band music played on the organ). An organ, such as Ingolstadt, in a live acoustic, such as Ingolstadt, makes it own demands on the player and the printed score. In this particular case, the player, the organ and the music are as one. The listener is engaged from the first notes to the last, not so much by the musical argument, but by the succession of episodes. You just have to hear what happens next.
