Here is a remarkable 35-stop organ of 1970, beautifully regulated and balanced, as fine a medium for Bach chorale preludes as may be wished. Wachet auf, with its twining dancing lines; Nun freut euch, a sparkling scherzo and O Mensch, bewein' soloed on a montre stop—these are the star turns. The chorale from Cantata No. 147, known to us as ''Jesu, joy of man's desiring'' has an obbligato on the regal stop, with the chorale thrusting forward on clear bright flutes. All the quiet pieces are satisfying, calm and steady. Some of the faster ones, however, from the Schubler collection, are uncomfortably head-strong and the pedal trills in Kommst du nun are like distant thunder (action noise, that is). The pedal part of the Magnificat prelude has all the pessimism of an old Mersey steamer. In the last prelude, Nun komm' der Heiden Heiland, the lower end of the pedal is so woolly that it almost vanishes. What I have pointed out as small technical deficiencies will, I know well, be meat and drink to very many organ enthusiasts. The sweet disorder in the dress is what these chaps are searching for. So I don't feel so bad about mentioning them.'
