"Warm" was recorded, mixed and mastered with producer/engineer Zach Grappone. Grappone and Schizzano worked together night and day to create the story of "Warm" sonically.
"Warm" is about being lonely. Feeling cold and knowing that one thing can make a person feel warm, human interaction. A lot of Sydney's music contains the theme of unrequited love and relationships ending, whether they were romantic or platonic. She wanted to convey the idea that sometimes you have to deal with being alone and finding peace in that and sometimes, that's not so easy.
