Wow. I have been listening to Prokofiev's second piano concerto and it is amazing. It is definitely one of my favorites (mind you, that isn't saying much because it changes every couple of weeks.)
Did you know that when he first wrote it, it was very strongly disliked? One critic even went as far as to say:
"To hell with this futurist music! What is he doing, making fun of us? The cats on the roof make better music!"
Each to his own, I guess. I think that its a masterpiece. It was pretty futuristic for his time though, so I guess that man can be excused.
