NYC disco-popsters fun. released Some Nights last year, and the disc instantly propelled them to fame, the Top 40 and six Grammy nominations. That success is due in large part to irrepressible, crazy-catchy hit "We Are Young," featuring Janelle Monáe—just try not to sing along to its anthemic, larger-than-life chorus. Tonight the group toasts its success with a blowout show at Radio City.
