Only Dro Video is Hydro's Uncle. 2010 was seen as the founding year, when they started as an almost unknown formation in the 101Barz Sessies studio session from BNN. The studio session gathered more than half a million views, wich was huge in that time. The three members had different musical qualities. They were known for their amusing gangsta rap, their own sound and live shows. Shortly after their performance for the online program, they signed a contract with the Mucho Dinero label from BNN presenter Rotjoch. The first mixtape they recorded was Hindabuilding! who became a big club hit for the group and made a lot of national and international publicity. Two other songs that belong to their club hits are Kill the bitch and Tot ik niet meer kan. In 2014, Hydro continued with a new formation named TimmyGang Lil' Kleine , Bokoesam, Kalibwoy Jowy Rose, Weeboy and King Yagri and MocroManiac started his own solo career. Around 2015 Hydro, Poppe T`Z and other Musicians started Team Ziel Entertainment. He also works alot with Producer Victorino Victomous
