Artists such as Jean-Michel Jarre, Mike Oldfield and Depeche Mode were the first to make such a big impression on him that he knew this is the genre of music he loves to hear. He started creating his own music in 1998 when he discovered that tracks can be created on his PC. It became his hobby and he spent all his free time making new sounds and tracks. Krzysztof doesn't have any musical education and he doesn't play on any instrument.
