Justin Louis Raisen is an American record producer, songwriter, audio engineer, and mixing engineer. His early credits included the works of Charli XCX and Sky Ferreira. He has also worked with Lawrence Rothman, Yves Tumor, Drake, and Lil Yachty.

Sky Tonia Ferreira is an American singer-songwriter, model, and actress. As a teenager, Ferreira began uploading videos on Myspace of herself singing songs she had written, which led to her discovery by producers Bloodshy & Avant and a recording contract with Parlophone in 2009. She released her first extended play, As If!, in 2011, which combined elements of electropop and dance music. Ferreira's second EP Ghost (2012), however, incorporated pop with more stripped-down song structures and featured collaborations with Jon Brion and Shirley Manson, as well as the critically acclaimed track "Everything Is Embarrassing", which she composed with Dev Hynes.
