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).
There are at least 8 bands / artists who have released music under the name "K2". 1. A dance-pop group (formed by sisters Kristina and Aleksandra Kovač) who became widely popular in eastern Europe during the 90's. 2. A German eurodance band, who are best known for their 1994 hit song Der Berg ruft.
