Notes

The song "The Man with the Corkscrew Eyes" features a sound clip from The Fever (The Twilight Zone) at the beginning of the song: "This machine... It's inhuman, the way it lets you win a little then takes it all back. It teases you. It holds out promises and wields you. It sucks you in and then..." The lyrics of the song "Headlines" reference the television programs Nightline, Twin Peaks, and The Simpsons, and the track features backing vocals from the late GWAR vocalist David Brockie.
