Do you know Icelandic band Sigur Ros? Their sound is ethereal. I imagine auroras would sing like that if they had sound. Icelandic culture has been Americanized, but Sigur Ros stays close to their original culture.
"Heima" means both "homeland" and "at home." Heima is the filmed record of Sigur Ros' concerts around their homeland in various locations including deserted fishing village, small country community hall, and so on. 99 percent of Sigur Ros' fans don't know what Iceland is like, so this is the chance to see.
