Linkin' Bridge
The members of Linkin' Bridge have known each other most of their lives and they are like brothers. Two of them are cousins, but all of them are buddies. This beat-boxing, acapella singing group from Louisville, Kentucky may look like tough guys, but they have surprised the judges with their smooth voices. Simon Cowell has said on the show that they are what America's Got Talent is all about. (Photo by: Vivian Zink/NBC)
