Part rapid-fire rapper, part confessional singer/songwriter, and part traditional folk storyteller, Ren makes music that can dart between genres as quickly as it switches from being insular to fantastical to universally relatable. Chronic health issues and mental health struggles were a big part of Ren's life from early on, and these became regular themes in his songs. His viral 2022 single, "Hi Ren," offered a perfect showcase of his unique patchwork of styles, and after hooking new listeners with that arresting track, he continued expanding in new directions on his 2023 album Sick Boi.
