Kiesza on Kimmel

EVERYBODY’S IN SHOWBIZ: If you happened to be walking down Hollywood Blvd. early Tuesday evening, you may well have been startled to see an athletic young woman moving rhythmically over the stars embedded along the sidewalk. In fact, that was Kiesza’s boldly imaginative salute to Tinseltown as she performed her worldwide chart-topper “Hideaway” on Jimmy Kimmel Live. And check out that tracking shot—and all that teeming humanity, no less. Props toKiesza, the intrepid cameraman and Island prexy David Massey, who signed this rapidly rising star. (7/30a)
