Tarrak stands as one of the most prominent voices in the Greenlandic rap scene. Through his lyrics, Tarrak conveys the connection between the political and the personal, delivering a razor-sharp and hard-hitting critique of colonialist thinking.

Tarrak broke through with his debut album FxGxS, where the track "Tupilak" in particular became a major viral hit. In 2019, he released the album “Josef Tarrak”, a deeply personal and autobiographical project that explored the depths of the soul through honest memories from his own upbringing. The album was later adapted for the stage for a theater play bearing the same name. In 2023, he released the single “Uummatima” with the Danish rap group “Suspekt”, and has since released several singles and most recently dropped “Pigalugu” in the fall of 2025.

Tarrak has received several awards, including the Talent Prize at the 2017 greenlandic music awards, the Prize of the Year at the 2021 greenlandic music awards, and the Government of Greenland’s Encouragement Prize in 2017.

In 2023, Tarrak became the first Greenlandic rapper to perform at Roskilde Festival, and when he returned to the festival in 2026, he received a six-star review from the music magazine GAFFA, which described the concert as "nothing short of historic."
