Mitski’s four-piece band, which included a drummer, guitarist, bassist, and keyboardist appeared right on schedule, and a few minutes later Mitski emerged onstage, walking slowly, almost meditative, to frenzied screams from the crowd. But on Tuesday she delighted fans with energetic and acrobatic dancing that at times was precise and carefully choreographed while other times became wild and flailing, with Mitski jumping and spinning across the stage. Mitski rarely talked directly to the crowd, except toward the end of the set, where she reached out to fans, declaring: “I love you, I love you, I love you, I love you.”
