Sematary is an American underground rapper who built a cult online following in the early 2020s through horror inspired mixtapes and a distinctive distorted sound. Associated with the Haunted Mound collective, his music mixes rap vocals with heavy, lo-fi production and dark imagery. Short clips from his tracks and performances circulate widely on video platforms and soundboards, where fans cut the most intense moments for edits and memes. This excerpt remains popular because it sums up that style quickly, making it recognisable even out of context to listeners familiar with the scene.
