Swedish prog-metallers Opeth join us this week. Formed in 1990 Opeth are a leading force in Scandinavian death metal. They're also renowned for creatively adding their own atmospheric influences to create their unique sound, including classical, folk and jazz. The guys come in to reveal how they're celebrating their twentieth anniversary, which includes a run of special shows they're putting on across the world where they'll be playing highlights from their extensive catalogue. Plus they divulge what their future plans are and how they manage to keep so inspired.
