Ultrademon has been played on NTS shows including Young, with The Bayou first played on 10 November 2017.

Ultrademon is Kansas-born and now Tokyo-based music producer, DJ, and pianist Lilium Kobayashi, formerly known as Fire for Effect. A founding member of the #seapunk movement, something that originated from a friend's dream, Ultrademon has attracted a loyal and cult following over the years with her positive vision of trans-humanism and work to raise awareness through seapunk. She formed her own imprint, Coral Records Internazionale, in September 2011. The label's music is less DJ oriented but still pays homage to the roots of electronic dance music.
