The Greek god Dionysus is such a good role model for binge-drinking, rave-going and alienated youth that you wonder why he's not used to lure them off the streets and into the theatre. He is, after all, the god of wine who induces frenzied worship among his followers, who then enjoy a good dance in his honour.

Then there's the reluctance of authority figures to accept his divinity, giving us in one handy god a symbol of misunderstood youth and their beer-swilling revels.

The German troupe Renegade Theatre has recognised his potential, and used him as inspiration for its new-ish piece Cage. It's set in and around a Perspex box, in which suited men seem to be mulling important matters (this represents the Thebans who reject Dionysus in the Euripides play). Enter Dionysus, a very god-like young dancer whose freedom and physical ecstasy goads the suit-wears.

Until this point, things look promising. The set is sleek, the music an evocative digi-jazzy-clubby mix, and the five dancers are gorgeous to look at. They are also able hiphoppers, the main style used.

However, director Markus Michalowski and choreographer Lorca Renoux haven't a clue what to do with them. The pair are simply unable to draw meaning from steps, nor can they translate the themes into convincing theatrical terms. This is a dull muddle.
