't Hof van Commerce ("The Court of Commerce") is one of the exponents of the wave of frithop groups that made a breakthrough in Belgium in 1998. This scene is a bunch of hiphop groups who are rapping in their own dialect.
The most peculiar thing about 't Hof van Commerce is the fact they rap in the dialect of West-Flanders, the coast province of Belgium. This makes them hard to understand by the average Flemish or Dutch people, but this "gimmick" could also be accountable for their increased popularity. The weirdness factor?
