Pailhead was a short-lived side project of the industrial metal band Ministry, which featured Ian MacKaye on vocals (formerly of The Teen Idles, Minor Threat, Skewbald/Grand Union, Embrace, and Fugazi and currently of The Evens). The band's sound was a dark combination of menacing industrial beats and hardcore punk, predating what Ministry would later do with Jello Biafra in Lard.

Considering MacKaye's inadvertent role in the establishment of the straight edge community and Al Jourgensen's legendary drug use, it was highly unexpected for them to collaborate.

Pailhead released the single "I Will Refuse" / "No Bunny" (released in both 7" and 12" formats) in 1987 and the 4-song EP Trait in 1988, both on the Wax Trax label. The CD edition of Trait also incorporates both sides of the "I Will Refuse" / "No Bunny" single. The drummer for "No Bunny" was Eric Spicer of Naked Raygun.

These tracks were later re-released on Ministry's odds-and-ends compilation Side Trax
