Hanussen emerged in the Budapest nightlife scene as a DJ around 2019. He was captivated by electronic dance music genres and the Budapest underground in the preceding years. In the beginning, he played at smaller illegal parties with friends, primarily spinning deep house sets. In 2022, he co-founded the Terra Kontra collective with friends, which hosts a club night series during the clubseason and a festival in the summer. His sets continue to draw from various house subgenres, often incorporating elements of dub house, deep tech, minimal, microhouse, UKG, and classic house sounds. He also strives to diversify his selection with influences from break, trance, and acid. At the end of the 2022 festival season, he and his colleague Kozmo D launched their musical concept, Blue Sun. Initially, they organized listening sessions and curated a mix series, but the project has since evolved into a record label.
