This ethereal, blurry ballad features both guitarist Romy Madley Croft and bassist Oliver Sim singing in unison. "It's one of the ones where I push myself the most to really sing," said Madley-Croft to Spin magazine. "Playing live so much, I got more confident with my singing."
The song's production includes floaty siren-like whistling sounds. DJ-producer Jamie Smith noted to Spin that for this, "I was experimenting with weirder electronic-music things."
