Demona is Tanza's (Constanza Godoy Díaz) Solo Project and was formed in 2007.
When a heavy metal musician has a daughter and that daughter is exposed to a life of metal (And enjoys it). It will lead up to a band that plays "classic metal" in this case Speed metal. The only thing that sets this band apart from the 100s of other revival bands is that Tanza plays all the Instruments. (Except her father plays lead guitar on The Apocalypse) For a solo project the songs are really well crafted making it a real joy to listen to.
This demo could of easily been made 20 to 25 years ago. Making it a must have/hear for any fan of 80s metal.
