The Berzerker's song "Forever" from the self titled album contains samples from Ed Kemper's testament, including "As I'm sitting there with a severed head in my hand, talking to it, or looking at it, and I'm about to go crazy, literally I'm about to go completely... Flywheel loose and just fall apart". It also contains samples such as "At the age of 24, he murdered his mother, then called police and confessed to having dismembered college co-eds for two years, as well as cannibalizing and raping their headless bodies" and "put her vocal cords in a garbage disposal, then threw darts at her severed head". These are all references to Kemper's murders...
