Last night on Late Night With Jimmy Fallon, Florence Welch, in the middle of a U.S. tour behind her nearly-a-year-old album Ceremonials, came through to sing a different version of the epic wailer “Spectrum (Say My Name).” This was an all-acoustic version, with Florence backed by guitar, harp, and string section. But she still fired up that bazooka of a voice. Watch it below.

Ceremonials is out now on Island/Universal Republic.
