Wolfgang Amadeus Mozart’s Piano Concerto # 20 in d minor, K. 466 is the most historically popular and influential among his keyboard concertos. Clara Haskil, a woman whose life was plagued by medical misfortunes, was able to identify with both the delicate and tragic aspects of K. 466. From her pure and self-effacing playing emerges her own short, stunning firstmovement cadenza, shuddering with forbidding bass trills and only a bare glimmer of grace and sun to penetrate the gloom.
