A new lineup was formed, with bassist Jason VieBrooks (formerly of Heathen and Grip Inc.), drummer Sasha Horn of Forbidden, and guitarist Marzi Montazeri (formerly of Superjoint Ritual and Philip H. Anselmo & The Illegals), with vocalist Kyle Thomas and guitarist Vinnie LaBella as the only two remaining original members.

Chris Nail, former drummer of the band, played drums on the re-recording.
