Their contributions: Sinners Prayer 

The incessant ranting and lurching rhythms of Distorted Pony could throw even the most seasoned noise rider. Topped with tortured vocals, plus a Cop Shoot Cop-like assault on metal sheets and trashcans, the Los Angeles band spit a paralyzing quart of venom with every note. The focal point of Distorted Pony (which formed in 1986 and called it quits in ’93) was Dora Jahr’s seething bass and the mix of screeching guitars from David U and Robert Hammer, creating a din that most resembled the Big Black caterwaul of sound. Not surprisingly, Steve Albini was behind the production board on both Pony albums.
