A pulse, not a blur: How Rick Rubin and Slayer reinvented metal music 40 years ago
Black Sabbath helped lay the foundations of heavy metal, but Slayer’s *Reign in Blood*, released 40 years ago, pushed the genre in a new direction. Working with producer Rick Rubin, the band shaped a fast, aggressive sound that remains influential and still feels modern.
Rubin had not produced metal before, but he felt that fast music with large sounds could blur together. He encouraged Slayer to use shorter, sharper notes and more space between them, creating what he described as a pulse instead of a blur. The article presents this recording approach as one reason the album helped reinvent metal.
- Slayer’s *Reign in Blood* turns 40.
