Spazmosity was founded in the fall of 1994 by the two guitarists Thelberg and Lamming. The band quickly evolved from playing covers to writing their own music in the death and black metal genré. After a few concerts Emanuelsson joined as a singer, and 1998 saw the addition of bass player Mordström. In 2003 their third and highly critically acclaimed demo Storm Metal was released. During all this time they gigged whenever possible and shared stage with, among others, Amon Amarth, Lobotomy, Vinterland, Watain, Throneaeon and Entombed.
