Book excerpt: Described in Germany as the 'most thought-provoking' book of the bicentennial year, Georg Knepler's acclaimed study of Mozart is now available in paperback. The book explores Mozart's life and works from many new perspectives, providing fresh insights into his music and the tempestuous times through which he lived. Based on a close reading of the family correspondence and a careful consideration of Mozart's entire musical output, the book sheds new light on the composer's creative psyche, his political leanings, his relation to the thoughts and currents of the Enlightenment, and the underlying basis of his musical expression.
