Johnny Hitman alias Roberto Stolzenburg started to get interested in soul music when he listened to Henry Storch at the Unique Club in Duesseldorf. He moved to Berlin and very soon he became a member of the Soulkombinat.
The Soulkombinat was founded in 1997 and has been running their legendary Funk & Soul parties since then in Berlin. Their mixing skills can be decribed best with a quote from Eddie Piller: “There is Soul without Funk, but there is no Funk without Soul.”
Due to his B.A. in Recording Arts he had the great opportunity to record the Dutch Funk band Lefties Soul Connection.
He spinned at Unique Club (Duesseldorf), Soul Inn (Berlin), Soulpower (Hannover), Soul City (Cologne), Soul Function (Malmoe), Soulful Turino (Turino), Funkexplosion (Moscow), Fun City Shingaling (St. Petersburg) etc. In 2007 he produced the Dutch Funk/Jazz band Leslie Nielsen and released the 1st Soulkombinat 7” “Petroleum”. Right now he is the Dj/Co-Organiser of “WE GOT SOUL” and "SOUL STOP".
