I agree with Arensky - emotional warmth in piano playing is all too rare these days. You don't hear much of it on the concert platform. Full marks for that. And I for one quite like the odd wrong note - people fuss far too much about them, but they actually are a reminder of humanity.
The question of the fidelity of reproducing piano rolls is long and very complex. I have lived with them for most of my life, so I have a good idea of the answers, but it's impossible to state them in a few sentences. This particular transfer is good; the original roll came from the private collection of Edwin Welte, the inventor, and was scanned and re-perforated a few months ago by a friend in Germany, who has the best set-up in the world for perforating Welte rolls. New copies tend to play better than old ones, though they need to be accurate, which this one is.
My London friend's Steinway-Welte is the best I have ever heard, and I have travelled the world listening to these things. There is a good upright in Austin, Texas, as well. Welte had a means of recording dynamics automatically - without lengthy explanations, you will have to trust me on that. Most of the writing on this subject is a load of junk! There may be instances of slight coarseness of dynamics, where the music is complex, but I'm sure you will still hear that it is a very sensitive performance.
There was a style of pedalling in the late 19th/early 20th centuries, and in particular in France, where the sustaining pedal was regarded as a coloration device, and was held down over harmonic changes. It sounds strange to us, but you can hear it on 78s as well as rolls. I'd like to look at this roll very carefully, because there are places where the pedalling seems a little blurry, but my instinct is that he probably meant it that way - it is more likely to be correct than not.
When I get time, away from expanding the Pianola Institute website (the new, incomplete one is at
www.pianola.org/exp), I'll send some lengthy and detailed posts to PianoStreet about player pianos and reproducing pianos. They are poorly understood by the general musical world - there are already in PianoStreet some very weird misconceptions of them.
Are you in London, Crazy? The way you play, you ought to hear, and would enjoy, some of the other pianists on roll. It might be arranged.
All the best,
Rex
