Eintritt from Waldszenen and the first movement of the Piano Concerto, both by Schumann. I adore both of these pieces but I find Schumann's music desperately boring, eclipsed only by Alkan in terms of sheer coma-inducing turgidness. I've tried to like Schumann's music, I have really, really tried but I just don't get what all the fuss is about.
I don't want to dislike it, he wrote a huge amount of piano music and to dismiss it all as not being worthwhile seems rather churlish. But try as I might, I just can't see this wonderful composer that so many people speak highly of.
