"Diesel Machine" was founded in the mid 90s by former musicians of the L.A. Heavies "World In Pain" and "Eleventh Hour". The hard Groove Metal of the band around Patrick Lachman (Halford, Damageplan) was compared with greats like "Pantera", "Crowbar" or "Machine Head". The only regular studio album to date, "Torture Test" was received enthusiastically by fans and critics alike and has retained it's absolute cult status to this day. 20 years later, the musicians got together again to celebrate their energetic, uncompromising extreme metal on "Evolve". "'Evolve' is a statement or even a branding for everything the band has dealt with over the years. This spirit of defiance and persistence is also expressed loud and clear in the lyrics.
