The Backstreet Boys’ first performance together since Kevin Richardson rejoined the group will be a special concert on ABC’s Good Morning America on August 31.

The concert will mark the first time the band has officially reunited since 2006. It will be part of the GMA 2012 Summer Concert Series in New York’s Central Park.

Richardson, A.J. McLean, Nick Carter, Howie Dorough and Brian Littrell made the announcement on Good Morning America Tuesday, appearing via satellite from the London studio where the quintet revealed they’ve been recording their new album.

“It’s our first time in the studio together, all five of us, since 2005,” Dorough said.

In 2006, Richardson, the band’s oldest member, left to pursue other interests. It was during a performance in London last April that the remaining Backstreet Boys announced that Richardson would rejoin them for a new album.

Carter said the recording sessions have brought them closer together. “We wake up. We have breakfast together. We’re not sick of each other at all,” said Carter. “It’s awesome. It really is. The vibe is fantastic.”

The band is working with producer Martin Terefe, who has also worked with Mary J. Blige, Train and Jason Mraz, among others, to record their new tracks.

The new album is expected to be released next spring, just as the group celebrates their 20th anniversary.
