D-Men was a Dutch rap formation established in 1997 under the name D-Men Squad. This was after a freestyle session they held on a basketball court in Diemen-Zuid. The original members of D-Men were rapper Lange Frans, his brother rapper Brutus and a childhood friend rapper-singer Bart Zeilstra better known as Baas B. They picked the name that sound like their home town Diemen. Many others joined in the formation, famous for its mixtapes De Straatremixes. D-Men also have their own record label named D-Men Entertainment.
