Roadrunner United was a project organized by the heavy metal record label Roadrunner Records to celebrate its 25th anniversary. It culminated in an album released worldwide on October 11, 2005, entitled The All-Star Sessions. Four "team captains" were chosen to lead 57 artists from 45 past and present Roadrunner bands, and produce and oversee the album's 18 tracks: Joey Jordison of Slipknot and Murderdolls; Matt Heafy of Trivium; Dino Cazares of Fear Factory, Asesino and Divine Heresy and formerly of Brujeria; and Robert Flynn of Machine Head and formerly of Vio-lence and Forbidden. The unprecedented project was the brainchild of Roadrunner UK General Manager Mark Palmer and Roadrunner USA VP of A&R Monte Conner.
