Jo and Stefani

After the simpler visuals of “Edge of Glory,” Lady Gaga appears in a video that brings back the showy costumes and imagery. She gets to play a cyborg and a mermaid in “You and I,” but I find two other new personas more fascinating: the simple, piano-playing blonde, and the male character “Jo Calderone.” It’s another good song, too; it’s a nice change of pace, sound-wise, a lighter but emotive track that gradually builds up to a powerful climax. Oh, Taylor Kinney, a.k.a. Uncle Mason the werewolf from Vampire Diaries, is in it, too.
