Thanks for this more recent version of Xaver Scharwenka's 4th piano concerto. While off-topic, I'd like to point out that he also wrote some very fine chamber music with piano. While not necessarily one of these, he also wrote an unusual piece (quirky perhaps) for piano,trombone and drums entitled "Five Leaves from Polyhymnia's Sketchbook" Op 89 which can be heard on you tube also.
