Originally hailing from West Chester, Pennsylvania, CKY has roots that stretch back to 1992, when friends Deron Miller (vocals, guitar) and Jess Margera (drums) met in high-school math class, eventually forming the group Foreign Objects together; they issued the five-song EP The Undiscovered Numbers & Colors on the Distant Recordings label in fall 1995. By the next year, the two had begun releasing less metal, more radio-friendly music under the name Oil, though continuing to record Foreign Objects work on the side. Picking up their third live bassist, Ryan Bruni, they released two more EPs, 1996’s Lifeline and a 1997 self-titled one.
