Onslaught - Power from Hell 1985 Children of The Revolution Records Signed Vinyl
Power from Hell is the debut studio album by English thrash metal band Onslaught, released in February 1985. Apparently confusion has arisen as to who coined the term Death Metal, as it was Onslaught who wrote their song 'Death Metal' in early 1984 and recorded the album version later in the same year, Possessed who recorded their song entitled "Death Metal" on their 1984 demo tape of the same name.
