Bjork. Other artists seem to like her and Europe seems to appreciate her but she's just under-appreciated in the "5-eyes" countries. In a way it's probably a good thing she never broke into the mainstream and stayed there. She's purely art for art's sake. She's remained completely true to herself and never sold out her artistic integrity or her values for money. She's done everything on her own terms and everyone who knows her work respects her for it. Being Icelandic seems to help immensely.
