"My knees are fine, my knees are fine. Yeah, no problem there. I'm actually jumping off even higher things these days," says Yannis Philippakis, lead singer of the British band Foals.

Philippakis is referring to his raucous live performances, which display a commitment to aerobatics that a trapeze artist might look twice at. Almost inevitably at some point in the show, Philippakis will climb to the top of the tallest structure on stage before launching himself into the air to the adoration of the crowd.

Other times he'll hop the barrier — guitar or microphone in tow — and let the audience carry him on its shoulders, followed by irate security guards who know they'll have to stage a rescue. The crowd loves it, and who wouldn't? Foals put on a hell of a show.
