The Backstreet Boys are an American vocal harmony group, formed in Orlando, Florida in 1993. The group consists of A. J. McLean, Howie Dorough, Nick Carter, Kevin Richardson, and Brian Littrell. They rose to fame with their debut international album, Backstreet Boys. In the following year, they released their second international album Backstreet's Back and their U.S. debut album which continued the group's success worldwide. They rose to superstardom with their third studio album Millennium and its follow-up album, Black & Blue.
After a two-year hiatus, they regrouped and released a comeback album Never Gone. Richardson left the group after the conclusion of Never Gone Tour in 2006 to pursue other interests. The group then released two albums as a quartet: Unbreakable and This Is Us.
In April 2012, the group announced that Richardson had rejoined them permanently, and in August, they made their very first performance as a reunited five-piece, closing out Good Morning America's Summer Concert Series. Their first album back as a quintet, In a World Like This, which was also their first independent album, was released in July 2013.
