Krzysztof Czas is a DJ and promoter from Poznań. From 2017, he plays under the pseudonym KRZone. He was brought up on Polish and American rap. Later, after the first visit to the now non-existent club in Poznań, Jack fell in love with electronic music, which continues to this day. He draws musical inspirations from artists such as Michael Mayer, Archie Hamilton, NTFO and Ben Rau. The style that he presents in his sets is house, tech house, deep and minimal. He always has great fun during performances and his expression strongly influences the public.
