Fuck Off were one of the first Spanish thrash metal bands to release an LP, and one of the most influential along with Legion. Fuck Off was their original name but they attempted to change it to Destroy in 1988 after releasing their first single, finally taking back the original name. The band split-up in 1990 and, according to some sources, Pep Casas registered the moniker without asking the other (founding) members and the former manager.

The band without Casas (Joe, Ringeling, Jackson, Miki) reunited in 2001 under another name since the copyright name was property of Casas. Hell on Earth rerelase in 2006 was made by Pep Casas without the consentiment of the other musicians that took part on the recording. Casas reunited the band in 2010 and asked the old members to join, but only Joe Bolta accepted.
