Between 1980 and 1985 a few Dutch Hip Hop records had already been released, but in 1986 Dutch rap duo MC Miker G & DJ Sven (Lucien Witteveen and Sven van Veen) had a major top 10 hit (often #1) across Europe with their "Holiday Rap", which sampled Madonna's "Holiday". That same year Dutch rapper Extince released his first record: Rap Around The Clock. Another 1980s group was the Osdorp Posse, who first started to record tracks in Dutch. But there is disagreement about who started rapping in Dutch between Blonnie B, Alex and the CityCrew, Dynamic Rockers, Def Rhymes and Osdorp Posse.
