Stop the presses! Fifth Harmony have officially joined the upper echelon of girl groupdom, making their BBC Radio 1 Live Lounge debut with a double performance that some might say hits just like a sledgehammer. True as their name, 5H stepped into the lounge in pitch-perfect harmony, singing even their collective “hello” like a chorus of angels greeting the world from a heavenly realm. Oh, but that’s not all. They proceeded to call upon the girl powers of yesteryear for a triumphant, scaled-back performance of their now-top-ten smash, “Work From Home.” And in keeping with the slayage (and Live Lounge tradition), they also worked the hell out of a cover, too, opting for a bluesy version of Elle King’s “Ex’s and Oh’s.” Have you ever witnessed a diva give herself chills with her own vocal acrobatics? Welp, now you’ve seen five.
