From February to April 1988, Vio-lence recorded their debut album, "Eternal Nightmare", at two studios: The Music Grinder in Los Angeles and Alpha & Omega in San Francisco. The album received mostly positive reviews upon its release in the summer of 1988, and peaked at number 154 on the "Billboard" 200, becoming the band's only album to enter that chart; this can be attributed to the album selling over 30,000 copies. Vio-lence toured throughout 1988 and 1989 in support of "Eternal Nightmare", with bands such as Testament, Voivod, Death Angel, Sanctuary, Nuclear Assault, D.R.I., M.O.D. and the Cro-Mags. The underground success of the album also caught the attention of several labels, including Megaforce Records (then-home to bands such as Testament, M.O.D., Anthrax, and Overkill), who eventually signed the band.
