Finneas, who released the solo EP Blood Harmony in October 2019, has also co-written and produced tracks for other popular artists like Justin Bieber, Selena Gomez and Camila Cabello. Originally written for Finneas’ band, “Ocean Eyes” sprung to life when infused with a 13-year-old Eilish’s ethereal vocals and became a viral sensation upon being uploaded to SoundCloud in November 2015. A second SoundCloud offering, “Six Feet Under,” was followed by her summer 2016 signing with Darkroom Records, which re-released both tracks as singles later in the year.
