am going to hear helene grimaud on the 11th (i believe). she's playing rach 2. will be interesting to hear for the first time.
i heard my teacher, carl cranmer, in philadelphia and thought of all the pianists i've heard - he was the best. i liked the intimate seating in the ballroom (near kimmel center) and actually prefer that over fancy halls. we were only sitting two rows back - and probably 5 feet away at the most. i sat on the piano keyboard side (of course). also, i liked what he played (faure nocturne #4 and other nocturnes). he has very intense playing and never seems to make a mistake. he's basically genius level. i would say i'd listen to him as much as ivo pogorelich or whomever comes to town. he plays in a 1/2 french, 1/2 modern way - discreet, tasteful, modern rep, modern approach, not too much motion, but a lot of emotion in the music.
once went to nyc with my teacher and a bunch of students to hear several piano concerts. that was also a highlight of my listening. to hear music in a really good concert hall (carnegie). it was amazing, even from the balcony what one could hear. despite this - i still prefer the intimate settings because you come away feeling like you ARE the music. you are wrapped up in it.
