Serial remixer and reliable party starter Calvin Harris has got his hands on the stems of “Spectrum” from last year’s Ceremonials album, and turned the track into a thumping, out and out disco joint that casts Florence Welch as diva in chief, kitted out in a glittering boiler suit, maybe even wearing roller skates. This is pretty much the opposite of what Dev Hynes did as Blood Orange for his slack, relaxed “Never Let Me Go” remix, but it is foot-stompingly awesome nonetheless. Take a listen, and have a little dance below.
