Haydn wrote keyboard sonatas for 'connoisseurs' and 'amateurs' throughout his career. Alternating bread-and-butter work and rich terrains of experimentation, they bear the mark of endlessly renewed invention. Alain Planès offers here a personal selection from Haydn’s output: from the experimental, sometimes anguished pieces of the 'Sturm und Drang'; through the refined and witty galanterie of the 1780’s; to the visionary masterpieces of the late sonatas, he brings out Haydn’s indefatigable spirit of adventure and infinite resource.
