The band was back then called Coven and it played Melodic Death Metal with some Black Metal influences. After quite a few lineup changes during the years, the band became known as Code Unknown. It has previously released three demo-ep's: Haunting Visions (2003), The Great Escape (2009), Room 667 (2011).

On this day, we have now released our fourth studio demo, Soul Circus. The Death Metal and Black Metal influences are pretty much gone as we have evolved more towards traditional metal with some modern wibes. We have now found our own original style and are more than happy to show it out to the world. The core of the band has played together over a decade so we feel more than ready to take over your souls & cities… (&beers & girlfriends).
