XXX: Three Decades of Roadrunner Records delivers a blistering overview of the label’s formidable first three decades of existence spread across four carefully assembled CDs. The first disc, “Foundations,” highlights the label’s early, reputation-building years with ultra-heavy tracks by Mercyful Fate, Carnivore, Deicide, Brujeria, Suffocation, Biohazard, Type O Negative and more. The second disc, “Horns Up,” sums up Roadrunner’s indelible impact on the metal scene of the 1990s with moshpit-detonating anthems from Slipknot, Machine Head, Sepultura, Coal Chamber, Fear Factory, and many others. The third disc, “And Metal For All,” brings the listener into the 2000s and up to the present with the pounding sounds of Killswitch Engage, Trivium, Dream Theater, Opeth, Gojira as well as a track from 2005’s “all-star” Roadrunner United album. The final disc, “Rock For The Ages,” focuses on Roadrunner’s hard rock contingent with tracks from mainstays such as Rush, Nickelback, Lynyrd Skynyrd, Theory Of A Deadman, Airbourne, Black Stone Cherry, and Korn featuring Skrillex, among others.
