O'Brien told NME
about the track, which transforms from a plaintive folk strum into a dance banger.
"The song 'Brasil' is the record in a nutshell. It's got this melancholy and intimacy at the start of it, but then goes into this joyful, beautiful, colourful place. There are moments of loneliness, sadness and withdrawal on there, but there are times of celebrating being a human being. I didn't want to make a record that was just melancholic. Melancholy is somewhere that you can slip into quite easily, whereas joy is the hardest thing to do on record. It's hard to have fun. It isn't something you can fake."
