Bulldozer dances in China

Two Chinese bulldozer drivers have combined their passion for rock-and-roll music with heavy duty vehicles to put on an unusual street performance in China's Changchun city.

Balancing the vehicle on its front wheel, while swinging the shovel from left to right was no easy trick, said 28-year-old driver Cao Bing.

He said it was difficult learning to control the giant bulldozers.

"It took me more than half a year to practice. It was very hard. I finally made it after tough training," he said.

Cao suffered several bangs to his head while developing his new skill as he neglected to take any security measures.

Cao is unwilling to share his secrets with others. He also worries it might be too dangerous for others to learn.
