A-based pop singer-songwriter, Rosie Darling, is known for her signature flowing melodies and gut-wrenching lyrics. She teams up with Swedish alt-pop artist Boy In Space on the emotional track “Nail in the Coffin,” which circles around a breakup without closure. Expanding on this, Rosie says “I wanted to write a song about a relationship ending on bad terms and needing to walk away from it even when you have unresolved conflict between each other. I think as someone who wants peace and resolution, it's hard to fully leave something when you don't feel like they've understood you or that you maybe didn't understand them, and you have to end it in conflict with each other. That's life sometimes though! We don't always speak the same languages and sometimes we have to walk away and end things unresolved and that's painful.” Rosie had wanted to collaborate with Boy In Space for some time and the two struck up a good rapport across the world thanks to the internet: “I think we would have been waiting years for this to happen if we both weren't willing to jump on a video chat and be a little vulnerable with each other.” The track starts with Rosie laying the groundwork for the dialog that ensues with a simple piano line and a dreamy, reflective echo. Then we hear Boy In Space’s bright timbre relaying another perspective, ultimately together their vocals fuse with complimentary tones creating a chilling force. Rosie’s clear vocals evoke some of her favorite contemporaries including Chelsea Cutler, Julia Michaels, & Olivia Rodrigo. Produced with collaborator Justin Gammella (FINNEAS, Ashe) & Freddy Häggstam (Chainsmokers, Bebe Rexha), mixed by Yianni AP (Alexander 23, Jeremy Zucker).
