Formed in 1985, Bay Area band Insanity were instrumental in metal's evolution from thrash to death metal. Drummer Bud Mills was a big reason why, as his so-called "1-1" beat presaged the modern blastbeat. The band's sound more than lived up to its name. Not only did it crank thrash up to frenzied warp speeds, it also displayed chops well ahead of its time. Insanity were legendary worldwide in the '80s metal tape trading circuit, with members of Carcass and Napalm Death citing them as an influence. However, the band never achieved proper success due to various misfortunes. Insanity's inaugural lineup comprised vocalist Joe DeZuniga, guitarist Dave Gorsuch, bassist Keith Ellison, and drummer Bud Mills. Their 1985 rehearsal demo, recorded with a Walkman and a stereo microphone in a garage, gained global renown in the metal underground. Napalm Death later covered "Fire Death Fate" on Leaders Not Followers, Pt. 2, and Snakepit magazine reissued the demo on 7" with its 15th anniversary issue. Insanity made its storied live debut on October 19, 1985, opening for Death in Bay Area metal hotspot Ruthie's Inn. However, two events derailed the band's rising career. The first was Mills' incarceration for ten months; the second was DeZuniga's death from heart disease on May 16, 1987.

After DeZuniga's passing, the band struggled to maintain a consistent lineup. A debut full-length, Death After Death, ensued in 1994 on German label M.B.R. Gorsuch was the only founding member still in the lineup, which included Matt Janko on guitar, Joe Landers on bass, and Prakash Sharma on drums. However, Sharma developed back problems and Insanity disbanded in 1994. In 1997, the band re-formed, with Lou Gilberto on bass and Mills on drums, and reworked Death After Death with new vocals and guitar tracks. This lineup yielded the three-song Sacrifixion EP, but the group folded in 2001.

This hiatus proved temporary also, as Insanity re-formed to play a mini-tour in California in 2005. That year also saw the release of From the Grave, a compilation on Parasitic Twin Productions, which collected the 1985 demo, Death After Death, and various 8-track demos. Napalm Death's Barney Greenway and Exhumed's Matt Harvey supplied liner notes for the compilation. Mills rejoined the band in early 2007 to play the Los Angeles Murderfest alongside fellow death metal pioneers Repulsion, Atheist, and Obituary. However, in September, Mills was diagnosed with esophageal cancer, and he passed away on November 14, 2007. At the time, the band was working on an album titled Visions of Apocalypse, and elected to soldier on using Mills' pre-production drum tracks. ~ Cosmo Lee, All Music Guide

Since that was written the band reformed and started touring. Since many of the arrangements of the songs on Visions of Apocalypse had changed since the pre-production tracks, Insanity recorded an official release of the album completed in 2015. The CD was released on Unspeakable Axe Records and the vinyl was released by parent label Dark Descent Records.
