During the late 1980s and early 1990s, the band members began working on various side projects. Key and Goettel were involved with The Tear Garden (a collaboration with The Legendary Pink Dots) and Doubting Thomas (an outlet for their non-Skinny Puppy instrumentals). The band Hilt, a collaboration between Key and Geottel, and Al Nelson, also started when Nettwerk challenged the group to produce an album for as little money as possible. Ogre struck up a friendship with Ministry's Al Jourgensen, having first worked together during the recording of the PTP song "Show Me Your Spine" (featured in the 1987 film "RoboCop"). The album, featuring Jourgensen's electric guitar work and backing vocals, drew mixed reception from fans. Despite these reactions, the album was a commercial success, selling 150,000 copies and receiving extensive airplay on college radio. The single "Worlock" – which featured samples of Charles Manson singing parts of the song "Helter Skelter" from The Beatles' "White Album", accompanied by a fragmented portion of the songs guitar introduction – helped to bring the band "massive popularity". A video produced for the song, featuring spliced-together footage from dozens of horror films and a statement denouncing censorship of the genre by the MPAA, was circulated widely as a promotional and bootleg item. The song "Tin Omen" was also released as a single and "Hexonxonx" received some airplay on alternative radio. In spite of the album's initial mixed reception, Brad Filicky in a 2003 issue of "CMJ" magazine named "Rabies" as a classic album, calling it "a masterpiece of the industrial genre".
