The Polish hip hop scene started in the early 1990s, due to the popularity of American rap.
Lee was from Kielce, but Warsaw soon emerged as a center for hip hop, after KOLOR, a radio station, began broadcasting Kolor Shock, hosted by Bogna Świątkowska, Paul Jackson, an African American expatriate, Sylvia Opoku from London, and DJ Volt, whose crew, 1kHz, became performing stars in their own right in 1995.
Now known as Liroy, the former PM Cool Lee released Alboom in 1995, which included the hit "Scyzoryk" (Penknife).
Psycho-rap lyrics are sung in a loud tone, sometimes even shouted, which is intended to convey emotions more effectively to the human mind.
Polish romanticism and fantasy literature were a strong inspiration for the lyrical layer of psycho-rap.
