Lyon Opera Ballet Grand Theatre, Cultural Centre Reviewed: June 3 This was the last dance performance in this year's Le French May Festival, but one of more than 300 events being staged in Beijing, Shanghai, Guangdong and Hong Kong as part of the France in China Year, which continues until September. French choreographer Philippe Decoufle created Tricodex for the Lyon Opera Ballet in 2001. The third work in a trilogy, after Codex (1987) and Decodex (1995), Tricodex was inspired by Codex Seraphinianus, a fanciful encyclopaedia created by Italian artist and naturalist Luigi Serafini. Fast-paced and seamless episodic sections blend dance, circus and visual effects in what Decoufle calls 'ensemble mathematics'. Philippe Guillotel's extraordinary costumes and Pierre-Jean Verbraeken's various suspension and flying contraptions challenge perceptions of gravity and extend the spatial and movement range of the human body. Rarely does live theatre manage to create such visual magic. Movements range from Neanderthal raw to the highly technical. This was Decoufle's first work with a company other than his own Compagnie DCA, and the exquisite dancers of the Lyon Opera Ballet were in full flight. The non-linear abstract sections seemed to leap time zones and theatrical genres, and were woven together by an enchanting world-music score. A homo-erotic Mr Universe send-up seemed misplaced, and the work suffered from a rather subdued ending, with a couple tracing the path of imaginary substances through the body. Young and old in the Grand Theatre were engaged and enlivened by the production.
