Though a legend in his own time, Bach wasn't appreciated by everyone in Leipzig. A certain J.A. Scheibe found cause for complaint against his music, calling it turgid, confused, and over-complicated. Donald Macleod looks at Bach's response to such criticism in his later years, and the concessions he may have made to the younger generation in his music. From the Mass in B Minor we'll hear the symmetrical Credo section, which stands at the centre of this huge work.
