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. The album project was coordinated by Lora Richardson and was mixed by Colin Richardson and Andy Sneap. The All-Star Sessions spawned one single and music video ("The End"). The DVD included with the CD purchase is a documentary of the "Making Of" the songs. It features the sessions of the four team captains making their songs.

On October 13, 2008, Roadrunner Records announced on its MySpace and on its official website that a two-disc DVD of a release party-concert, featuring songs from the album performed live, would be released on December 9, 2008. The DVD features the full concert and a documentary.
