Eternal Nightmare is the debut album by the San Francisco Bay Areathrash metal band Vio-lence. It was released originally in 1988 on MCA Records' Mechanix sublabel. A limited 10" promo single was released, with two tracks 'Eternal Nightmare' and 'Phobophobia'; the release was quite unique, as it came in a sealed plastic cover, containing (fake) vomit.[3] Shortly after, thrash metal innovators Slayer released a single in a similar format, but with fake blood and alternative rock band The Revolting Cocks released a single with fake semen.
