Al Jourgensen has stated that the name Houses of the Molé is a tribute to the Houses of the Holy album, released by Led Zeppelin in 1973.
Primarily a solo project by Barker, Lead Into Gold featured occasional guest performances by his Ministry bandmates Al Jourgensen and Bill Rieflin.
W.E.L.T. was a briefly extant side-project between members of industrial bands Skinny Puppy (Nivek Ogre) and Ministry (Al Jourgensen and Michael Balch).
According to Al Jourgensen's interview with Kenny Herzog of Spin magazine, "PermaWar" is based on Rachel Maddow's book Drift: The Unmooring of American Military Power.
