Pianist Grete Sultan (1906-2005) is one of the most extraordinary artists of the 20th century. Raised in a Jewish upper-class household in Berlin, she managed to escape Germany in 1941 after being banned from the concert stage. In New York, she met John Cage with whom she maintained an artistic collaboration for her whole life. Wergo's set Piano Seasons contains her recordings, some of them being released for the first time, of piano works from widely different epochs. Baroque, classical, romantic and contemporary music meet here, finding common ground in the interpretation of this exceptional artist.
