In 1747, composer Johann Sebastian Bach, elderly and deeply tied to an old world of myth and mysticism, accepted an invitation by the young, ambitious warrior-king Frederick the Great of Prussia.

It was a fateful meeting, where the old, dark religious world of Bach faced off with Frederick the Great, son of the Enlightenment, a powerful monarch tuned to empiricism and reason. Frederick the Great presented Bach with a fiendish musical challenge, the frustration over which led Bach to compose “A Musical Offering,” considered one of the great works in the history of music.

In telling their encounter story in a new book, author James R. Gaines says their meeting was a clash of ages, of fundamental world views and understandings of life that still rages on.
