Lady Gaga proves that she isn't real, she's theater. "And you and I, this is just a rehearsal." Opening with an awe striking monologue in character as Joe Calderone about art, expression, love and truth, she demonstrated again last night that she is a performer of the avant-garde above anything. VMA winners and influential pop artists like Nicki Minaj and Katy Perry clearly mimicked the Gaga of the past two years, but she moves keep moving forward.
