As a frontwoman, Follin exudes subtle starpower, the clear focal point at stage center surrounded by four seemingly interchangeable dudes with shoulder-length hair. She kept returning to the same simple shoulder shakes and dips, but that was appropriate for these songs that inspire some movement but not all-out dancing. Anything else would have been overdoing it, and Cults excels at knowing how far to go. After ending its set with early hit “Go Outside,” the band simply stayed onstage and announced it would play an encore without the wholly unnecessary walkoff. “Oh My God,” another lightly poignant song, ended things after 45 perfectly charming minutes.
