I listened to most of the recitals on the radio. My favourite was also Rem Urasin. He played the four Chopin Mazurkas Op. 24 in the semi-finals, and the intensity of his playing was incredible. I was at the Opera House for the Mozart concertos, and Rem was outstanding - it sounded as though he was speaking to each person individually with his playing. I wasn't that impressed by John Chen's Mozart.
For the 19th/20th Century concertos, I thought Daniel Hill's Prokofiev was outstanding. I didn't think Rem played the Tchaikovsky that well. John Chen's Rachmaninoff was definitely very good. Although since the last round involves both the Mozart and the 19th/20th C concertos, and I thought Urasin's Mozart was so good, and his Tchaikovsky was not so bad, that I was very much surprised when the 1st prize eventually went to Chen.
I attended Urasin's recital at Hunters Hill Town Hall (incredible - a solo piano recital was sold out!) and it was superb. He's rather dedicated to Chopin.
I also attended Chen's recital at the Sydney Town Hall. I find his slow playing needs more breadth and intensity - he tends to lose me during his slow playing and I start to fidget. But Chen is incredibly relaxed when he performs. It's like he has no nervousness at all.
Of the pianists that didn't make it to the finals, I was really impressed by Masataka Takada - he has this wonderfully clear touch that was so beautiful.
Well, that's just my two cents.
