Clockcleaner was a punk/noise rock band from Philadelphia, Pennsylvania. The band consisted of John Sharkey III on vocals/guitar, Karen Horner on bass, and Richie Charles, Jr. on drums. The trio had drawn comparisons to The Jesus Lizard, Big Black, Nirvana, Flipper, and even noise band Whitehouse. Their influences include Cromags, gg allin, Sun Ra, Brainbombs, Albert Ayler, and the first Skrewdriver LP. As they progressed, they began to more heavily embrace a sludge-like post-punk influence.
