18,000 fans swarmed to Rockefeller Center this morning to see Lady Gaga perform a half-hour set as part of the Today show’s Summer Concert Series. Gaga looked lovely in a white bra, goggly white glasses, and a head of cropped hair; she performed the smash hits “Bad Romance” and “Alejandro” as well as a brand new song from her forthcoming second LP. The song is called “You and I” — it’s a slower piano jam, perhaps signaling a new direction for the dance-pop queen?Watch the video above to hear “You and I.” Skip ahead a few minutes if you don’t want to listen to Meredith Vieiria.
