Sematary & Ghost Mountain were a signature rap duo from Northern California most well-known for their dark, gruesome lyrics and aggressive distorted beats. They began uploading music to Soundcloud around the end of 2018 and created two mixtapes together. In 2019, they formed the rap collective Haunted Mound in 2019 to release their music.

Grave House (2019) was the debut work for both artists and formed the staple horrorcore black metal sampling vibe that would shape the Haunted Mound sound up until Sematary’s Screaming Forest mixtape. Despite attempts to move away from the early discography, references to this original work still pop up occasionally in recent works.

Their second mixtape, Hundred Acre Wrist became well-received by fans old and new alike for its distorted witch house-focused experimental production and unique tone. It was the last major collaboration between the rap duo, however, the very last song between the two was “GOIN' MORDOM” off of Rainbow Bridge 3.

As of 2023, Ghost Mountain has seemingly quit music entirely, as he deleted all his social media accounts in mid-2021 and made claims that he is unwilling to make a return to music. He instead wants to go a different direction with his life and focus on college.

Ghost Mountain’s absence also marked a sonic change in the Haunted Mound, as Sematary began to add new members (such as Hackle, the first post-Ghost addition) and the further shift towards Chief Keef Chicago drill production and flows.
