Reign of Terror is a demo album by American death metal band Death, released in October 1984.

[1] An interview of the band's lead vocalist and guitarist Chuck Schuldiner was later re-released in 1985 as “Reign of Terror II” which includes a set from October 1984.

[citation needed] Along with Death's demo Infernal Death, Reign of Terror "influenced the Death metal scene tremendously", as "their low and guttural nature would become the staple of the genre".

[2] Author Ian Christe, in his book Sound of the Beast: The Complete Headbanging History of Heavy Metal, noted that Death's demos "became as heavily shared by tape traders as any well-established act in metal".

[3] The fan club version of the demo also features a song titled "Zombie Attack" between "Summoned to Die" and "Witch of Hell".
