From Santiago, a hand grenade of thrashing verocity and  death metal aggression, "When Sanity Becomes Insanity" channels  the wild South American sound of the late eighties, recalling elements of early Sepultura with the purulence of Vulcano. Add in some Morbid Angel churn. and you've got an perfectly executed intersection of death and thrash.
