Wilhelm Friedemann Bach – Fuga in do minore (1770)

Wilhelm Friedemann Bach (22 November 1710 – 1 July 1784), the second child and eldest son of Johann Sebastian Bach and Maria Barbara Bach, was a German composer and performer. Despite his acknowledged genius as an organist, improviser and composer, his income and employment were unstable and he died in poverty.
This work has been composed in one of his «darkest» periods, when he was looking for a post between Halle and Braunschweig (without success) before moving to Berlin.
