Roadrunner United was a project organized by iconic hard rock record label Roadrunner Records to celebrate its 25th anniversary, culminating in the U.S. Billboard Top 200, UK Albums, and Australian ARIA Albums-charting original The All Star Sessions. Four "team captains" (Slipknot's Joey Jordison, Machine Head's Robb Flynn, Fear Factory's Dino Cazares, and Trivium's Matthew K. Heafy) were chosen to lead 57 artists from 45 past and present Roadrunner bands. It was truly a heavy metal family affair — and then some! Additionally, on December 15, 2005, a concert celebrating the project, album, and anniversary took place at the Nokia Theater in New York City. That star-studded event featured multiple musicians, both past and present, from Roadrunner bands — as well as musicians that did not originally perform on the All-Star Sessions album. The set list consisted of some of the most popular and famous songs released by Roadrunner Records, as well as some of the original songs from the project's album. The "core band," which performed on the majority of the songs, consisted of the aforementioned Cazares (Fear Factory), Adam Duce (Machine Head), the late Paul Gray (Slipknot), the late Joey Jordison (Slipknot, Murderdolls), Andreas Kisser (Sepultura), and Roy Mayorga (Hellyeah, Stone Sour).
