A musician, instrumentalist and producer from Bydgoszcz, he  works primarily in electronic music. His artistic practice draws  on a broad range of experience in sound: formal musical training, many years spent producing electronic music, and work as  a sound engineer for a wind orchestra.

Together with Mateusz Wysocki, he cocreated the IFS duo. One  of its major releases is New Legends, an album recorded with  the rapper M.STO and released by JuNouMi Records in 2025.  Another notable strand of their work is IFS meets…, a three-part  series bringing IFS together with the vocal artists MA, AGF and  spalarnia. Ostrowski and Wysocki curated and produced all three  releases.

Krzysztof Ostrowski performs solo, as one half of IFS duo, and in  a variety of other line-ups, many of them rooted in Bydgoszcz’s  alternative scene and the artistic community that has emerged  around Mózg.
