This week Wikimetal brings the great producer and composer, Roy Z! A musician that left his mark on several careers, like Bruce Dickinson, Helloween, Rob Halford, Sebastian Bach and Sepultura.

Roy told us about how he first met Bruce Dickinson and how it was to work with him, the main differences between Dickinson and Rob Halford, and about the experience of producing an album with Andre Matos.
