8. David Bowie
British rock vocalists often open their mouths to sing and suddenly there isn't a hint of an accent. This is not at all the case with David Bowie. Much like Ray Davies of the Kinks, Bowie sounds distinctly British when he sings. He also has an absolutely stunning voice with great range. Just check out this video of "Life on Mars" from Bowie's appearance at Fashion Rocks in 2005.
