Composed after he settled in Vienna, Mozart’s `Auernhammer´ sonatas, k. 376, 377 and 380, are the first fruits of his freedom from Salzburg serfdom and a sign of his new, revolutionary spirit. Multiple awardwinners Andrew Manze and Richard Egarr capture the sense of orchestral colour and concerto-style interplay which runs through these works. A rarely-heard fragment, k. 403, is included as a delightful bonus.
