In a fantastic recording too. By my estimation, almost two hours of the four and half hours of music is music/arrangements I don't have (and 50+ minutes of what remains is the Bach transcriptions).
I also have a copy of volume 1 - unfortunately, I've not yet had a chance to give it a spin! I note that the ongoing series on Grand Piano has yet to get to most of the material on these discs. When funds allow, I shall buy volume 2.
