The xx titled the album Coexist
to get across unity and togetherness. Sim explained to 7Digital United Kingdom
: "There was talk of calling the album 'Together' but, even though it's such a simple word, for me it's very 'nice' and conjures up quite a twee image. I think we wanted to do something with a darkness to it, that was a bit more honest about how relationships can be."
He continued: "Romy found the word 'coexist' when doing artwork research. She was looking at the way oil and water make those beautiful rainbows when mixed together and found a line about it: 'Oil and water don't mix, they agree to peacefully coexist.' She's a bit of a romantic and really liked that, and saw a mirror in what we do – in that we're three separate people and we only make this music when we come together. So the word 'coexist' seemed a lot more honest and it felt right."
