Out of the ashes of Los Angeles, California's Devastation, which formed in 1986, Sadistic Intent began in 1987. The band quickly changed its line-up, then just as quickly released a few rehearsal tapes and in early 1989 released the Conflict Within demo, which the band pushed and distributed through the internationalunderground scene. Eventually Sadistic Intent signed with a rising label, Wild Rags Records. In 1990, the Impending Doom EP was released and a few tours followed in Mexico as well as the United States. The following year, after bitter disputes with the label, they moved on and self-released a limited edition 7-inch EP A Calm Before The Storm. Due to line-up problems, the band would not do any live appearances until 1993. In 1994, Sadistic Intent recorded the Resurrection MCD with bassist Bay Cortez singing for the first time. After sorting out another line-up problem in 1996, they recorded a tribute song to Celtic Frost for Dwell Records. In 1997, they then released Ancient Black Earth as a limited edition MCD through their own record label, Dark Realm Records. In 1998, a split 7-inch EP with the German black metal group Ungod was released through the German record label Merciless Records. 1999 saw more tribute recordings and releases from Sadistic Intent. One was for a Dwell Records tribute to Los Angeles metal band Slayer and the other for California's Possessed, which featured original Possessed front man Jeff Becerra on vocals. By 2000, Sadistic Intent licensed its Resurrection of the Ancient Black Earth LP to Germany's Iron Pegasus Records, which also released the Morbid Faith 7-inch EP in 2002. Eventually by 2007, Jeff Becerra asked Rick and Bay Cortez if they would be interested in doing more Possessed songs and it was then when Becerra decided to call it Possessed, and Sadistic Intent became the members of that band from 2007 through 2010. After that split-up, in 2011 it was announced that drummer Nick Barker had joined Sadistic Intent; however, logistically it became too difficult to take place. After taking care of that line-up change with the addition of current drummer Arthur Mendiola in 2011, the next Sadistic Intent release was recorded in 2013 to be released in 2014 titled Reawakening Horrid Thoughts, a 12-inch laser-etched EP through Iron Pegasus Records. Throughout the years, Sadistic Intent has toured in various countries around the world such as Norway, Brazil, Finland, Mexico, Germany, Chile, Holland, Italy, Switzerland, Denmark, Greece, Belgium, Australia, Singapore, France and the USA.
Sadistic Intent is linked to the record label and record store Dark Realm Records in Downey, California, since the owners of the store, Bay Cortez and Rick Cortez, are both Sadistic Intent members. The store has been compared to the black metal gathering site and record store in Norway. The record label of the same name has released Sadistic Intent's albums, as well as albums by Dark Angel, Pentacle, Witchmaster, and Draconis.
