SERIOUS in intent but humorous in tone and filled with spellbinding and extraordinary dance elements, Chronicle of a Floating City features two dance extravaganzas choreographed by Hu Jia-lu and Yuri Ng. The dance dramas are about contemporary life in different floating cities and how we are trapped in our own world and memories. Inspired by Mahjong, the most popular form of gambling among the Chinese, Yuri Ng choreographs his new ballet with the intent to explore the game's historical origin, the philosophy of chance and probability, game rules, strategies and the superstitions surrounding it. Ng was born in Hongkong and began his dance studies at the age of six. In 1982, he graduated from the National Ballet School in Toronto, Canada. From 1982-83, he received a scholarship to study at the Royal Ballet School in London, England. While he was there, he participated in the Imperial Group Adeline Genee Award and won the gold medal. His choreographies have been staged in England, Canada and Hongkong. Hu Jia-lu's Fragile is a mixed media dance production which explores the atmosphere of city life. The production is ominous yet playful, pessimistic but also heart-warming. Hu is a modern dance pioneer in China. He attended the Martha Graham School of Modern Dance and later studied choreography at the Alwin Nikolais Dance School and Murray Louis Dance School. His works have been staged in many cities in China, other Asian countries and the United States. Presented by City Contemporary Dance Company, Chronicle of a Floating City will be staged at the Shouson Theatre at the Hongkong Arts Centre from June 3 to June 6 at 8 pm. Tickets at $100, $80 and $50 (half-price tickets for students and senior citizens) are available at all URBTIX outlets. For more information, call 3229616. For telephone reservation, call 7349009.
