Gesaffelstein launched his professional career with his debut EP in 2008 through OD Records, establishing his distinct dark and experimental sound. The following year, he co-founded the independent label Zone with collaborators The Hacker, Alex Reynaud, and David Rimokh. His early work gained significant commercial reach when his track ‘Viol’ was utilized in prominent advertisements for Citroën and Givenchy in 2012. That same year, he received industry recognition with a featured cover on DJ Mag alongside Brodinski.
‘Hyperion’ featured high-profile collaborations with The Weeknd on the track ‘Lost in the Fire’ and Pharrell Williams on ‘Blast Off.’ Later that year, in October 2019, he surprised fans with the release of the EP ‘Novo Sonic System.’ Gesaffelstein’s track ‘Orck’ was selected as the pre-intro and outro theme music for Apple’s October event in 2021. He continued to innovate through collaborative EPs, releasing ‘TW20 50’ with KayCyy in 2022 and ‘TW2052’ with the artist in 2023. His third full-length album, ‘Gamma,’ was announced in February 2024 and released in March 2024. Looking ahead to 2025, Gesaffelstein is set to make a significant impact by co-producing and co-writing the track ‘Killah’ on Lady Gaga’s forthcoming album, ‘Mayhem,’ and will feature live with her at Coachella.
