Death 'n' roll is a term used to describe the sound of death metal bands which incorporate rock elements to their music. The term is a portmanteau of death metal and rock 'n' roll. The achieved effect is that of death metal's trademark combination of gruff vocals and highly distorted detuned guitar riffing with elements reminiscent of 1970s hard rock and heavy metal. Notable examples include Entombed and Gorefest.
