Hello Martin Eastick
I've just finished hearing the Hyperion reissue of Scharwenka's chamber music and I am greatly impressed. I was happy to see that the IMSL project offered the two trios, piano quartet and cello sonata on download, and being able to follow with the scores only enhanced my pleasure, appreciation, admiration. However I quickly noticed that Seta Tanyel and Colin Carr play a later, substantially revised edition of the Cello Sonata (I saw only after that you do mention it in the liner notes), while it is the original edition that is downloadable. Since you provided the scores and parts, can you give me tips as to how to find the revised score? I've search the net but in vain; the best result I obtained (and it is appreciable) was, following a "last-resort" search on your name, to find this blog. I am not a performer, just a listener. See my review on Amazon.com (Discophage).
Incidentally, among my own unsung works and composers, Zarebski's Piano Quintet. Nearly contemporary with Scharwenka, by the way - and very similar in style to his chamber music.
