Brazilian singer Georgia Brown (probably not her real name) is the current Guinness World Record holder for the largest recorded vocal range. She can scream those crazy high notes Mariah Carey-style, but Georgia makes it her specialty.
Unfortunately Georgia cannot sing a spiritual anywhere near as well as Mariah. Watch her cringe-worthy attempt after the jump.
(Thanks to Brendan J. for the tip!)
Holy fuckballs. Frightening.
