That instinctive and effortless control can only be found in the genius among all genius. The power of his music never lie in sweet tone, but in the subtle control of the innumerable small and large variations of tonal pallete, vibrato, time and dynamism. This could only be the gift of God for a man of any age. He also played the Bach Suite No.5 before the intermission. He played the Third last time he came but this time his Bach was technically much more untidy.
Bach demands a lot of awkward technique such as double-stop.
I found that he was already too tired after playing the Brahms. His conception however was worth noting. The fifth one meant solitude for him. You can actually felt that gradual slide into a deep darkness starting from the Prelude. He played them dramatically and emphatically of their meaning.
