Coldplay's Chris Martin recently wrote about Björk as one of 100 Greatest Singers in a Rolling Stone article. Here's what he had to say:
When you land in Iceland, you feel like you're somewhere a bit magical. Maybe it's the volcanic activity, maybe it's the dried fish, but something's going on: Everyone seems to be extraordinarily beautiful, and everyone appears to be able to sing. Their singers are so far ahead of everyone else — especially Björk. Her voice is so specific and such a new color. Now that she's been around for 20 years, everyone forgets quite how extraordinary she is. She could be singing the theme from Sesame Street, and it would sound completely different to how anyone else would do it, and completely magical.
She first crossed my radar on "Big Time Sensuality," from that video where she's on the back of a flatbed truck. I really got into her on Homogenic, largely because there's so much space left for the singing. On that album, there are strings and beats, but it isn't very full musically, so she has to do all the dynamics and everything. If you really want to hear what she can do, listen to "It's Oh So Quiet," from Post: She can go from zero to 60 faster than any other vehicle in terms of singing. And then to angry.
