Josi Miller was born in Leipzig-Connewitz and gained her first experience as a DJ in the East German subculture. Parallel to her studies at the Bauhaus University Weimar, she played bigger and bigger stages throughout Germany over the years - her sets were already pushing genre boundaries back then. Josi moved to Berlin in 2017, having long been a protagonist of the Homegirls-podcast. She accompanied Trettmann for years as a tour DJ, while also touring as a solo artist. She DJs in Cape Town and Maui, at Radio Rudina in Vienna and FOUNDATION.FM in London, at about:blank, Institut für Zukunft and Uebel & Gefährlich, plays shows from MODULAR to MELT, Gurtenfestival Bern to Openair Frauenfeld and Feel to Fusion.  

During the pandemic, Josi honed her producing skills and founded the electropop duo Import Export - in a team with KLAN-musician Stefan Heinrich; with “Snacks” and “Meds”, this constellation produced two highly acclaimed EPs. This was followed by Performances at the Zeiss Planetarium in Berlin and at the Primavera Pro in Barcelona with Import Export, their own stage at the Splash!-festival, a project trip through South Africa initiated by the Goethe Foundation, countless workshops for Flinta* and various productions for artist friends à la Jolle or Zugezogen Maskulin. For around two years, Josi has been hosting the ARTE-format Chat with a DJ, in which she regularly welcomes artists such as Marlon Hoffstadt, Anja Schneider and Acid Pauli. 

In the fall of 2023, Josi decides to tackle a solo album during a creative camp in Limoux, France. The first fragments of the large-scale project are created in the company of trusted musicians such as Fatoni, Aywing, Lambert, Torky Tork and Beach People. In 2024, Josi moves to post-punk icon Gudrun Gut in the Uckermark for several weeks as part of a funding program - this is where her plans take shape. At the end of an intensive exploration of her own psyche and countless hours between synthesizers and beat software, “4 Stages Of Sleep” is released - a debut album that fuses breakbeat, pop and electronica. It will be released in October 2025 by Grönland Records and will soon be performed live on stage.
