FIRMA, a Polish hip-hop group known for its street rap style, was established in 2000 in Kraków by founders Tadek and Kali. The group expanded in 2001 when Popek and Pomidor from Legnica joined, soon followed by Bosski. Notable for its fluid lineup, FIRMA has seen various rappers participate either as guests or full collaborators in studio recordings. This frequent change in members is partly attributed to the past criminal involvements of several FIRMA members. A significant moment in the band's history was the inclusion of the track "Jeszcze Firma nie zginęła" ("Firma is not yet defeated") on Popek's solo album "Monster," featuring Tadek and Bosski as guest artists.
