Chopin - Welte-Mignon Mystery 4

This is not an historical recording. Yet mysteriously the music is performed in an interpretation which is historically authentic down to the last detail. The key to this mystery is: The original performer was present at the recent recording session, but not physically: The music is heard on a modern Steinway. Never has music stored in the Welte-Mignon system sounded so "right" or so good - so unadulterated that it need not fear comparison with a living pianist! (See detailed text in the enclosed booklet. Can you tell the difference: dead or alive?)
