I think a mix of compositions and two or three good improvisations would be nice. This particular piece I will definitely use; this performance is about good enough as a "live" performance recording, but there are a few places (especially in the last movement) where I wouldn't mind doing another take for cosmetic purposes. Also I noticed a beat missing, quite inexplicably, in a bar in both the first and second movements. I've not really sat down and listened to this "analytically", in a "studio production" sense, and doing such things is invaluable but often quite depressing! Of all my compositional work, this is probably the one I've really thought about intellectually (I had to! - with the exception of the Dies Irae the piece is broadly monothematic, everything being derived from the two related falling motifs at the start of the first movement), whereas paraphrases tend to get developed improvisationally. I've made several small changes since it was first "finalised", and as a result, I think I have genuinely thought about every note in the piece! It's nice to hear the suggestion of a full disc; my teacher said exactly the same thing a few years back, and I also like the "freedom" when the pieces are ones you've written yourself!
