'Power From Hell' is the debut studio album by pioneers of British thrash metal, Onslaught, originally released in 1985. 'Power From Hell' mines territory similar to that of early Slayer, making these thrashers one of the first bands to begin refining a sound into what would later become death metal. This important piece of metal history influenced and defined the early works of many bands such as Exodus, Slayer and Metallica.
