The group from Japan is on a mission to expand the conventional meaning of "cute." Their performance included synchronized dancing, pom-poms and matching pink uniforms, with a heavy, angular sound.
As she settled in for this stripped-down set, Taylor Swift looked out over the office. "I just decided to take this as an opportunity to show you guys how the songs sounded when I first wrote them."
The vibrancy of the band can feel childlike and candy-coated. But the group's songs are more about the pain of entering adulthood and leaving some of that sweetness behind.
