fter leaving the legendary Thrash act Slayer in 1992 for personal reasons, Dave Lombardo opened up his own shop called Grip Inc. shortly later. Gus Chambers (ex-21 Guns and other British Punk bands throughout the 1980s; vocals), Bobby Gustafason (ex-Overkill; guitar) and Jason Viebrooks (ex-Heathen; bass) joined him, but within a few months Gustafson was found to be incompatible and left in favor of Waldemar Sorychta (ex-Voodoo Cult Project/ex-Despair; guitar; also producer for Tiamat/Unleashed/Samael/Asphyx/Gathering/Moonspell/Sentenced). Their debut album, Power Of Inner Strength (1993), was a blast of Hardcore and Thrash that gave them a name in the industry.
Their line-up remained stable through the 2 track EP Ostracized (1996), and their last to date, Nemesis (1997). In late 1996, Viebrooks was fired from the band after the recording of Nemesis and replaced by Vancouver, Canada bassist Stuart Carruthers after being recommended by Devin Townsend from Strapping Young Lad. Lombardo would bounce around the music industry doing odd jobs and projects while the band was on hiatus, even working with Slayer again until 2003 when he made the announcement that a new Grip Inc. album was in the works.
