What to read after Evening in the Palace of Reason?

"Twenty years later, Frederick's personality having congealed into a love of war and a taste for manhandling the great and near-great, he worked hard and long to draw "old Bach" into his celebrity menagerie. He was aided by the composer's own son, C. P. E. Bach, chief keyboardist in the king's private chamber music group. The king had prepared a cruel practical joke for his honored guest, asking him to improvise a six-part fugue on a theme so fiendishly difficult some believe only Bach's son could have devised it. Bach left the court fuming. In a fever of composition, he used the coded, alchemical language of counterpoint to write A Musical Offering in response. A stirring declaration of everything Bach had stood for all his life, it represented "as stark a rebuke of his beliefs and worldview as an absolute monarch has ever received." It is also one of the great works of art in the history of music." "Set at the tipping point between the ancient and the modern world, the triumphant story of Bach's victory expands to take in the tumult of the eighteenth century: the legacy of the Reformation, wars and conquest, and the birth of the Enlightenment. Most important, it tells the story of that historic moment when Belief - the quintessentially human conviction that behind mundane appearances lies something mysterious and awesome - came face to face with the cold certainty of Reason."--BOOK JACKET.
