Sarah Brightman

Sarah Brightman's performance during the opening ceremony of the 2008 Summer Olympics was one of the most watched in history, turning an estimated billion-plus people into Brightman fans. Here, the storied vocalist wraps her impressive pipes around new-agey Christmas classics and thumping Euro-disco numbers (for those who like their holiday numbers to have more of a modern mall feeling to them). Take another look at that odd cover photo -- the once human, pleasantly rounded Sarah has been turned into a vampy villainess from a '80s sci-fi movie, black leather outfit and all.
