Even Gräwe's piano playing, which I'd been quite impressed by in recordings, seemed to me perfunctory and uninspired. Thumbs down, in other words.
Which recordings were you impressed by? And do you know more about the proportion of improvisation/composition in his work?
(I know, I'm going to have to do some 'research' of my own now.)
The only disc I have is "Traces of Memory", which while not Parnassus-ific, does have a quality of its very own unlike anything I've heard. Does remind me, strangely, of Bill Hopkins, though more homogeneous, more glib certainly, and less meticulous about shaping every single note. Can you corroborate that or am I too far in left field?
