Rachmaninov plays his famous prelude. Recorded in 1919 on Ampico system. Ampico was the most advanced version of piano roll's systems which contained also track with recorded dynamics in hexadecimal code. In 90's it was transfered to PC and reproduced by Boesendorfer 290SE piano. You can see that piano here on my previous post http://www.youtube.c om/watch?v=k-rqOJDo0 -8
