Dennis Bouwman grew up in the Crooswijk neighborhood, to later become one of Netherlands hiphop pioneers under the name of Def Rhymz. He passed away at the young age of 53 as a result of a heart condition.

Local artist Ché Lanser honored his life with a portrait at the nearby legal wall of Schuttersveld. Much to his dismay this mural was sadly painted over after a short while. Lanser spoke about wanting to create a longer lasting memorial in local and national news, and that's where Karski comes in. He offered to help Ché to make this new mural possible. Just over a year after the death of the rapper and MC they started their work here.

They created two designs for the locals to choose from. This design with the two faces of Dennis Bouwman was chosen as the most popular. On the left side we see the loving Dennis as his family knows and remembers him. On the right we see the slightly crazy Def Rhymz as the rest of the country knows him.

The poem accompanying the artwork was written by local poet Derek Otte.
