The Backstreet Boys are an American vocal group, formed in Orlando, Florida in 1993. The group consists of A. J. McLean, Howie Dorough, Brian Littrell, Nick Carter, and Kevin Richardson. They rose to fame with their debut international album, Backstreet Boys (1996). In the following year, they released their second international album Backstreet's Back (1997) and their debut album in the United States which continued the group's success worldwide. They rose to superstardom with their third studio album Millennium (1999) and its follow-up album, Black & Blue (2000).
After a two-year hiatus, they regrouped and released a comeback album Never Gone (2005). Richardson left the group in 2006, several months after the conclusion of Never Gone Tour to pursue other interests. The group then recorded and released two albums as a quartet: Unbreakable (2007) and This Is Us (2009).
In April 2012, the group announced that Richardson had rejoined them permanently, and by July, had started working on their next studio album. The group also made their very first performance as a reunited five-piece in August, as part of Good Morning America's Summer Concert Series.
The Backstreet Boys have sold over 130 million records worldwide, making them the best-selling boy band of all time, and one of the world's best-selling music artists.
