Mighty Imperials: I can't dance to this modern racket

I'M SUPPOSED TO BE WATCHING the debut UK gig by New York's Mighty Imperials, but, off to stage right, three black men are turning themselves into human Catherine wheels, and it's proving to be something of a distraction. Callisthenics-wise, it's somewhere between an insouciant, perfectly balanced cat leaping from rooftop to rooftop, the Watusi, and the crowd at an early Grandmaster Flash gig.
