I was just about to post something about the pilot of the DH3. I think he has a small magnet on the co-pilot's seatbelt buckle. He swears it makes the plane fly better. He doesn't have any proof, and the co-pilot thinks he's goofy, and there is no (known) reason whatsoever that the magnet affects the aerodynamics - but dangit, he paid $2,000 dollars for that thing at AeroPhile.com, and he is POSITIVE that plane is flying better now...

Alright, enough of that, sorry...heh heh...

Assuming you're serious...My only recording here is Alfred Brendel, 1975 or so. Tempo's just right for me. There are so many great recordings though - it's impossible to prefer the same one two days in a row!

But the intro has lots of silence and fading notes - perfect for this type of "testing." The beginning of the d-minor("tempest") 1st movement has similar good quiet moments.
