3. Thom Yorke
I am not convinced now, nor ever will be--no matter how many bios or certificates of identification may be thrust in front of my nose--that Thom Yorke is actually a member of the human race. The Radiohead vocalist is, I'm fairly certain, an extra-terrestrial. How else could he have such a strange, unnerving, beautiful, honest, contemptuous, heavenly, alien voice? How else could he help craft musical tracks from an odd assortment of memories and sound that catapult the listener through a darkling warp tunnel of one-part exploration and two-parts ecstasy? How else could he think that that's really how you spell Tom and really how you spell York? How else? He's an alien. He's an alien with a voice to kill and die for.
