This chapter explores the direct experiences of renowned record producers, working with metal music, to construct an in-depth understanding of the genesis, and development, of recorded metal music. Technological democracy has changed the experience of making metal records, affording creative flexibility and control that would historically have been out of reach, technologically and financially. Multitrack technologies and fragmented production processes are also examined. Framed by the experiences of producers that have shaped the recording careers of artists such as Black Sabbath and Judas Priest, this chapter links the direct experiences of record-making to musical, sociocultural and technological development.
