Kosi
Kosi, born Marcin Patryk Kosiorek, is one of the important figures of Warsaw’s hip-hop underground and a long-time pillar of JWP/BC.

Artist Trivia
- For a long time, Kosi was more of a cult figure than a mainstream one, because despite his strong influence on the scene he waited many years before releasing a classic solo album.
- Besides JWP/BC, he also worked in projects such as Blackbook with Ero and Jetlagz with Łajzol, which shows that his career grew more through crews and collaborations than through a standard solo path.
- He is deeply connected with graffiti culture, and sources note that he co-created the zines “Linja” and “Uwaga” and was associated with magazines such as “Moment” and “Ślizg.”
- His solo album debut only arrived in 2021 with “IS.OK,” released through Def Jam Recordings Poland.
