The official musical debut took place thanks to Waco and his "Świeży Materiał" (Prosto 2001). It was on this album that the track "Beztrosko", signed with the abbreviation JWP, and the hit "Graffiti" (promoting "Świeży Materiał" with a spectacular street video), in which Kosi appeared. The year 2007 finally brought JWP's first full-length album, recorded with Ero, Doni, Foster and Kosi. "Number Jeden Wróg Publiczny" was remembered by the listeners thanks to the expressive energetic singles: "Bądź Misstrzem", "Chcę być tam" or "Pogódź się", and the weekly "Przekrój" recognized "Wróg Publiczny" as one of the five best Polish hip-hop albums of all time.
