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!
