William Gibson shared this video on his blog. I am not sure what part of the Arctic this is from. The games are held in Canada. So I am imagining this type of singing is from somewhere in the Canadian arctic rather than Greenland. Awesome throat singing in either case and very non-western approach to music which is startling and refreshing to hear.
The story has a multi-threaded approach where the author is trying to approach the Magnetic North Pole to endure the cold at the weather station there. There is also the story of the people of Resolute Island who were forcibly relocated from Inukiajak on the Ungava Peninsula by the Royal Canadian Mounted Police in the 1950s. This video reminded me of the girls on Resolute Island in the novel. The third thread in the novel is a tie in is how the British expedition led by Franklin failed and then was lost to the ice.
