Jeremiah Mark (born May 7, 2006), better known by his stage name Lucy Bedroque, is a rapper, producer, and songwriter based in Los Angeles, California.

Though their music career began with creating lo-fi beats, they became involved with many online communities around the “digicore” scene during the COVID-19 lockdown. This inspired them to experiment with using their own voice under the alias loru.

In 2021, they adopted the moniker lostrushi and became part of the #GREED collective alongside artists like *67, yuke and kaystrueno. While in this group, they released his most popular track to date, “maple” in November of that year. However, their drive for creative independence led them to leave the collective and focus on solo experimentation.

By 2022, Lucy began making waves with viral releases like “true perspective” and “syxx anthem,” all while refining his unique sound. Drawing from a diverse range of influences—including alternative genres like sigil, rock, metal, and shoegaze—their work is shaped by inspirations such as Dir en grey, Linkin Park, POiSON GiRL FRiEND, twikipedia, and Hi-C. They frequently incorporate elements like Nintendo game soundtracks, cinematography, and visual kei, blending them with a strong emphasis on storytelling.

One recurring theme in their work is the concept of sisters, which he elaborated on in a 2023 interview with No Bells:

The entire story behind “Sisters” is for each of the sisters to meet at a common ground and function in unison. They’re a representation of my own personal emotions, so all my different aspects are essentially tied to one big theme or idea: acceptance.

They released their debut album, SISTERHOOD, on June 23. This project further developed their artistic universe with new concepts like glutmother, an alias symbolizing their gluttony, both literally and metaphorically.

On March 6, 2024, they rebranded from lostrushi to Lucy Bedroque, a move that sparked mixed reactions from fans. They addressed their frustrations during an Instagram live, playfully brushing off the criticism and explaining that the new alias better represents themself and their music. That same day, he teased his upcoming project, Fête de la Vanille—a 6-track EP that takes heavy influence from Japanese music genre Shibuya-kei—which was released on October 4.
