Arcade Fire multi instrumentalist Richie Reed Parry contributed to several tracks on High Violet
including this one. Guitarist Aaron Dessner told The Quietus
: "The big thing he did was that he heard me working on the music for 'Conversation 16', and he said, 'I have an idea!' So he went in and sang – his father is a choir director so he knows multi-part singing – he sang this seven-part vocal, it's all him layered. That's beautiful. He's this very lovely, unassuming person – when you see someone's musicality inserted into the room, you're like, 'woah!' And that was great – he was just staying at my house, it wasn't like we planned to work on it like that."
