Peter Kops (born 1967), known professionally as Extince (also known as "Exter-O-naldus" or "De Exter"), is one of the first Dutch language rappers, or Dutch Hip-Hoppers to achieve a top-40 hit in the mainstream Dutch music charts. His hit song "Spraakwater" rose into the top-ten, and was a historic breakthrough for Dutch-language rap & hip-hop – even more than for the artist himself. Extince was born as Peter Kops in Oosterhout, Netherlands. One of his biggest musical influences as a child was Creedence Clearwater Revival.
