His exceptional touch and sense of phrasing, his deep and personal understanding of the most varied repertoires, or even the legendary trio he formed together with Jacques Thibaud and Pablo Casals, made Alfred Cortot the greatest pianist of his time. Master of many disciples, notably the brilliant Dinu Lipatti, Samson François and Clara Haskil, Cortot also had a lasting influence on the Russian piano school through Samuil Feinberg and Heinrich Neuhaus, the latter himself being the revered teacher of Sviatoslav Richter.

All of the recordings in this set had undergone careful sound restoration in 2012, in order to respect as closely as possible the original sound. The remastering was carried out under the expert control of Mr. Guthrie Luke, a former disciple of Alfred Cortot who attended many recording sessions by Cortot. These recordings do not represent a "complete" edition: the many rolls engraved by the artist for Duo-Art, Aeolian and Pleyela labels have not been reproduced here, most of them doubling the 78-RPM repertoire. The first recordings are acoustic; and the ones with an electric microphone appeared as early as 1926.
