XXX Rottweiler Hundar (XXX Rottweiler dogs) is an Icelandic hip hop band founded in the late 90's. Originally named 110 Rottweiler dogs as 110 was the postal code of the hood they represented. Their lyrics are very often concidered cruel and offensive but witty and well composed at the same time, but sometimes the lyrics and songs are laid back and humorous. Their rap is hardcore and most often rapped in Icelandic, although rarely in English or Danish.
