Happy B'day Pollini. Two of my favourite recordings were the sonata in b-flat minor and the Chopin etudes. I usually use the Etudes as a reference point while listening. I even have his sonata recording in my ipod. I enjoyed his recording of Chopin's Heroic Polonaise op53. Some parts were different to what I was used to hearing such as the giant rolled chords, which he played in blocks. Another honorable recording was the Petrushka which I think is the best recording possible.
