Roadrunner Records has put together a groundbreaking record to mark the label's 25th anniversary. This full-length release is a master class in hard rock/metal. Boasting 57 artists from 45 of Roadrunner's past and present bands, the album contains original tracks that are collaborations between numerous Roadrunner stars. Four central musicians were originally chosen to produce and write the songs: Joey Jordison (Slipknot), Dino Cazares (ex-Fear Factory/Brujeria), Robert Flynn (Machine Head), and Matthew Heafy (Trivium). These four musicians play on the songs they have written and have also assembled a unique team of artists to appear on each track. In order to cover as wide a spectrum as possible, no musician has played for more than one writer/producer and each song features a different vocalist. In addition to these stellar teams of musicians, there are also special additional tracks from ex-Roadrunner artist Josh Silver--Type O Negative's longtime producer/keyboardist. In the spirit of the project, Silver has included Roadrunner artists on his tracks as well--Opeth's Mikael Akerfeldt appears on the Silver-written "Roads."
