KK or Kristján Kristjánsson is an Icelandic blues and folk musician. His stage name is pronounced "cow cow."
KK was born on March 26, 1956 in Minnesota, USA, but later moved to Iceland with his family. He attended music school in Malmö, Sweden for four years and then played his way across Europe, returning to Iceland in 1990. He has been nominated for the Gríma Prize twice and has been awarded the Icelandic Music Prize twice.
In 2007 he toured to Shanghai with Magnús Eiríksson ("Maggi") and Óttar Felix Hauksson in advance of the release of their next recording there and in Iceland.
The singer Ellen Kristjánsdóttir is KK's sister. He composed "When I Think of Angels" and he and Ellen perform it in memory of another sister who died in a car crash in 2002. A video of them performing the song produced by the Icelandic Red Cross is used for Red Cross fundraising. He and Ellen also perform Christmas music every year in Reykjavík.
