Florence and the Machine

You’re more or less guaranteed a rousing experience with Florence Welch and her disco-gospel Machine. But expect to throw your hands in the air just a little more exuberantly tonight if the U.K. siren does her new Calvin Harris remix of “Spectrum,” from last year’s Ceremonials. It’s a pounding electro-house banger about how she found love in a hopeless place. With the Maccabees.
