Has anyone played this song, or does anyone know of a recording? I was at my local music shop and saw it sitting there, so I flipped through the piano score and immediatly noticed how hefty the damn thing is. The bass part is the most difficult thing I've ever seen -- Dragonetti and Bottesini do not seem to compare overall. The first movement is a beast, with the whole Concerto being a half an hour in length. It's ironic because I've been searching for so long for a modern piece that was actually difficult, and the perfect piece was right under my nose. If anyone's a fan of discordant goodness or is tired of all that 150 year old crap, seriously consider this baby.
