DVD Of Note: The History of the Pianoforte

"For the first time, music lovers can see and hear instruments representing three centuries of piano building — all on a single video. From the oldest surviving piano, an instrument of 1720 built by Cristofori (the inventor of the pianoforte), to a Bösendorfer computer grand (which allows a friendly technician to correct the pianist's errors), the entire family lineage is here." Link. Just in time for my birthday !! :--)
