would love a guy who said "When listeners laugh at a concert of my symphonic music, I am not in the least bit shocked. In fact, I am pleased.” His music is almost schizophrenic, going from hilarious to grotesque to heartbreaking to tender and lyrical.
The 1st concerto is a lighter piece, filled with wonderful moments of laugh-out-loud hilarity and an almost hysterical and uncontrollable forward motion. Argerich was perfect -- completely destroying the piano during the more aggressive parts and snap-changing into a lyrical and subtle sound when it called for it. Awesome, awesome stuff. Here's Argerich playing the 1st movement, which is a good little snap-shot of the whole piece.
They also played Prokofiev's 1st piano concerto, which he wrote while still at Conservatory. I really liked the piece -- it definitely felt like early Prokofiev and he still hadn't gotten some of the kinks out yet. But the piece was a ton of fun and really showcased Argerich's virtuosity.
