This electro-disco track about a lover who gives, “such sweet nothing,” features the vocals of Florence Welch from Florence + the Machine.

The singer previously linked up with Harris when his remix of her Ceremonials track, “Spectrum” shot to the top of the UK singles chart. The song was premiered on Chris Moyle’s BBC Radio 1 breakfast show on August 28, 2012.

The Vincent Haycock directed video was filmed over two days in a Working Men’s Club in Dalston, London. It features Welch as a singer in a small, dingy, Serbian nightclub. Surrounded by a violent life and fearful of her future, Florence unleashes a ferocious performance.

When this debuted at #1 on the UK singles chart it broke a run of second place finishes for Calvin Harris, as his previous four singles as lead artist had all stalled at #2.

This was the first single that Welch had sung on that reached the top 10 of the Hot 100. Her previous best chart ranking had been the #21 position of her own group’s Florence + the Machine’s “Dog Days Are Over” in 2010.
