The group’s creative process is rooted in atmosphere and emotion. Much of their early music was written in Joscha’s grandaunt’s old art-filled room, a space full of books, plants, and history. That environment influenced how they approach music today: treating each track as a setting that blends sound, design, and feeling.

Joscha and Finn first connected through piano lessons as kids. Encouraged by their teacher, they began writing songs for themselves and for friends. Over time, their sound grew and their audience expanded. By 2023, they had gone viral with their single ‘What Love Is’. The track, with its dreamy mix of disco, yacht-rock, and synth-pop, became a huge hit on Instagram and TikTok, appearing in over a million social media videos. This wave of attention introduced Zimmer90 to listeners around the world.

This year, Zimmer90 reached another milestone: their song ‘what a life’ was chosen for the Bose × NME C25 mixtape. The C25 project revives NME’s famous C-Series tapes from the 1980s and 1990s, which were known for spotlighting fresh talent before they broke big. Now reimagined in partnership with Bose, the C25 introduces 25 rising artists from around the world across different genres.

Zimmer90’s inclusion places them alongside a diverse group of international acts, showing how their dreamy indie-pop sound resonates far beyond Germany. NME described ‘what a life’ as a breezy, late-summer anthem that perfectly captures the mixtape’s vibe. For Zimmer90, being featured in C25 is more than just a nod of recognition, it’s a chance to reach new global audiences and stand shoulder to shoulder with other future stars.

With their debut album ‘Interior’ set for release in September 2025, Zimmer90’s inclusion in the C25 mixtape feels like the perfect bridge between their breakthrough moment and their next chapter. It’s both a celebration of how far they’ve come and a preview of the world they’re about to share with an even larger audience.
