Two evenings of the complete Beethoven Piano Concertos in April. FIVE Beethovens opens with the exuberance by pianist Hui Ling on the first concerto in C, while the delightful No. 2 in B-flat by Dr. Cheng Wai. The adamant No. 3 in C minor will be served by Prof. Mo Cheung-Yu while the spiritual No. 4 in G Major mastered by Prof. Chang Tao. Only the “Emperor” in E-flat eventually led by play-conductor KaJeng.
