Kosma Król is a standout voice in Polish rap, with deep roots in freestyle. After a breakthrough 2025 – featuring two albums, a sold-out tour, and performing with Jimek in Japan – he is now one of the most sought-after young artists. Fresh off his massive, sold-out “Widowisko” show in March 2026, Kosma brings his unique flow and charisma to WROsound. His performance is the perfect soundtrack for a summer night, blending raw energy with modern beats.
