Street dance sets stage on fire International troupe of B-boys "Blaze" are performing at the Sydney Opera House summer family show. Jessy, Lagaet and Machine pose for a photo. Picture: Adam Taylor Source: The Daily Telegraph FROM the outset, it's clear Blaze aims to please. "This is no ordinary show," says MC Tony Thrills. Indeed the audience are free to take photos during the performance, shoot video and if the mood takes them, get up and dance. Cue 1 1/2 hours of blasting energy, hi-octane music and guilt-free family fun that culminates in an audience free-for-all dance-a-thon. The street dance show has already been seen by audiences of 200,000 in Europe and Asia, and for its Australian premiere makes a pitch for the feel-good hit of the summer. Fast and fresh, Blaze has a cast of 16 that moves through a furious mix of dance styles and pop music -- tap, popping, lyrical and b-boy battles exploding on stage to the sounds of Justin Timberlake, Kanye West, Lady Gaga, Ellie Goulding and David Guetta. The b-boys, Jessy, Lagaet and Machine, along with Thrills, are the undisputed stars. Their street dance skills are impressive as they egg each other on to outdo each others' moves, but they also demonstrate the discipline of trained dancers. They segue seamlessly from their roles as daffy stage hands, to demanding routines set to pulsating music such as Wiley's Take That and follow it up with displays of physicality as projections of water drip down the set. It's a show-stopper. Their relentless energy is matched by Thrills, whose Atomic Food routine has the whole audience on their feet. In fact there's no better measure of a show than feeling the collective envy of the audience during the encore, when a young girl was invited on to the stage to join the cast for their last dance. Her reaction was the perfect expression of what the crowd was feeling; she jumped in time, delivered fist-pumps of pure joy and left the stage positively beaming.
