Deathcrush is an EP by the Norwegianblack metal band Mayhem. It was released on 16 August 1987 by the Posercorpse record label, and was the first studio release by any band in the Norwegian black metal scene.
Though influential to black metal, its lyrics and sound were largely influenced by early death metal bands. After vocalist Dead joined the group, the lyrics adopted darker topics and Euronymous started rejecting most death metal bands as their lyrics turned towards "social awareness" and "normal" topics instead of death worship; he "wanted things to be more serious and extreme". Dead stated that the lyrics "aren't bad at all, but they are later what would become gore and trendy".
In 2008, Daniel Ekeroth wrote, "The two visionaries [Aarseth and Per 'Dead' Ohlin] pushed each other further into darkness, and sometime in 1990 they finally adopted the Satanic image that would become so crucial for the genre [...] It's well documented that Øystein initially was very into death metal and grindcore."
