This assignment aims to pick randomly a kind of music and to represent it. I had metal music, and I wanted to focus on a specific one : the "viking" metal. I was inpired by Nordic mythology with Odin, the God of Gods, accompanied by ravens, his totem animals. HIMMELSK means "celestial" in Norwegian, in tribute to Viking deities. The geometric symbol is a Viking rune, an Old Norse letter. It's called Othalan, it means "estate".
