My friend's pianola has a mountain of recordings sitting on top. The rolls of paper – with perforated holes where the notes should be – live in their own little box with the name of the song printed on the end. Some of them weren't recorded so long ago, but most were. The name of the person who played the piano that made the recording is printed under the song title. I can't tell if the pianist was good or bad but they get your toe tapping.
