Back in (Germany), Klein decided to leave high school before graduating, instead founding his own event agency, Smartcorehotel.

By a fortunate coincidence he was introduced to singer Sasha, who engaged Klein to write for his second album and helped him to sign a contract with Warner Music.

Teaming up with Syke n Sugarstarr and DBN from Hamburg in 2010, Klein reached the dance charts in several countries, including Britain, Spain, Austria, France, staying at No.
