No, I was talking about those Sorabji pieces.
And, of course (as all those who know about the subject already realise), you were referring to JONATHAN Powell.
Sorabji, as you may know (but others may not) thought very highly of all three Medtner concerti and indeed reviewed the première of the last one.
I, too, find all three to be truly individual and wonderful. I was commissioned several years ago to compose - of all unimaginable things - a cadenza for the third one (to be placed between its second and last movements) for its Italian première; it took an awful lot of soul-searching before I could even begin to think why the piece should even have one and quite a bit more to figure out how, if it did, it would come across as anything other than a blot on his highly personal musical landscape, but I eventually plucked up suifficient courage (or foolhardiness, or something) to overcome this and went ahead and wrote it - only to find that the performance was cancelled (albeit not because of my cadenza, I'm relieved to report) and I don't believe that the piece has been played in that country to this day...
Best,
Alistair
