The live demo by INSANITY that was circulated all around the world in the underground tape trading scene of the mid 80's. From this recording Insanity became recognized for using the early blast beat innovated by Bud Mills. Members of notable bands such as Napalm Death and Carcass mentioned Insanity as an influence after having this demo! These copies are duplicated from remastered recordings and sound better than the orginal from 1985.
