In D-Men

In 1997, Zeilstra was a founding member of a band alongside rapper siblings Lange Frans and Brutus Frederiks as he was a childhood friend of the two. After a freestyle session on a basketball court in Diemen-Zuid, they created hiphop collective D-Men. The English pronunciation of "D-Men" is similar to the Dutch pronunciation of the name of their home town. As D-Men they released their first single entitled "Zoveel Mensen" ("So Many People"), and in 2001, they won a talent contest that was organised by Stichting Grap ("Joke Foundation") in 2001. In later years, many artists joined D-Men, namely Brace, Yes-R & Soesi B, Negativ and DJ MBA.
