Happy Birthday Mozart Hong Kong Sinfonietta City Hall Concert Hall Reviewed: January 20 Hong Kong celebrated Mozart's 250th birthday with an electrifying performance of works by the Austrian composer last Friday. Led by the baton of American conductor Scott Yoo, the performance was enjoyed by a packed audience at the City Hall Concert Hall as well as radio listeners at home. Under the guidance of Yoo, a Mozart specialist, the orchestra displayed discipline and vigour from the first phrase of the 32nd Symphony that opened the concert. The tempo was generally brisk, but effective and clean. The wind and brass sections played with great chamber quality, blending well with soaring strings, and the conductor's meticulous attention to detail didn't prevent a sense of spontaneity. The great rapport between the conductor and the orchestra was evident in the two concertos that followed the opening piece. Award-winning Romanian pianist Cristina Marton played with scintillating technique and poetic touches in the K.466 Piano Concerto. The famous theme in the second movement was beautiful. Although the orchestral accompaniment at times seemed over-eager, the biting precision - such as the big tutti entry after the cadenza in the first movement - was impressive. The Second Flute Concerto, too, showed a great rapport between the orchestra and its principal flautist, Eilidh Gillespie. But it was the 39th Symphony that ended the concert on a high note, with the Harvard physicist-turned-conductor's call for clarity and precision evident throughout the piece. It was an inspired performance, with a majestic introduction, followed by the singing strings in the second movement, the exquisite wind trio in the third and a vigorous finale. The applause would have pleased not just the performers, but also the birthday boy who never heard this symphony performed.
