Combining a thoughtful pop approach with hip-hop elements and dark trap leanings, Paula Hartmann's songs capture the zeitgeist of urban life and Gen-Z angst. Kickstarting her career, she appeared as a child actor in films through the 2010s. In 2021, she released her first singles, "Nie Verliebt" and "Truman Show Boot," and signed with Four Music, which released her debut album, Nie Verliebt, in 2022. Collaborations with musicians such as Casper, Haftbefehl, and Trettmann heightened her profile. Her second album, Kleine Feuer, released in March 2024, had a much darker sound than its predecessor and reached number two on the German charts.
