Julie Christmas is an American musician from Brooklyn, New York. Christmas is her legal middle name; she was named so after the fact that she was born on Christmas day. She is the former lead singer of defunct Brooklyn-based noise rock band Made Out of Babies and the former lead singer of defunct post-metal supergroup Battle of Mice. In 2010, she released a critically acclaimed solo album titled The Bad Wife, and in 2016, she became a featured member on the Swedish post-metal band Cult of Luna's album Mariner.

Cult of Luna is a Swedish post-metal band from Umeå founded in 1998. Their style of music is similar to contemporary bands Neurosis and Isis. Cult of Luna was signed to Earache Records in the early 2000s and released five albums, including the commercially successful albums Salvation (2004) and Somewhere Along the Highway (2006). After an extended period of inactivity, Cult of Luna returned with its Indie Recordings debut Vertikal (2013) and companion EP Vertikal II (2013), both drawing inspiration from Fritz Lang's 1927 film, Metropolis. In 2016 the band released their space-themed collaborative album, Mariner, featuring American vocalist Julie Christmas.
