The very first meeting between Grubson and Hip-Hop took place in 1993, courtesy of his older brother - DJ Hudy, who started to promote 'black' music in his hometown Rybnik while organizing Hip-Hop parties - so called 'Rapoteki'. Grubson started to take Hip-Hop more serious at the end of 1997 when his first group "Po-3na Roznica" was formed (Grubson, Max, Rav). Tracks were recorded in the cellar onto the 1/4 inch recorder. 2 years later 'Jaco' joins the group and from now on they call themselves "Czwarta Zmiana" AKA "Tworca Sklad".
