With their next album, 1988's Hangin' Tough, the group's image had toughened up and they had the material to support it. New Kids were awkward and enthusiastic on their 1986 debut, which wasn't surprising considering that the oldest members were barely 16 years old. The group went on to sell over 70 million albums worldwide, generated hundreds of million of dollars of concert revenues, and roughly paved the way for acts like Backstreet Boys and *NSYNC. Assembled in Boston in 1984 by producer Maurice Starr the members consisted of brothers Jordan Knight and Jonathan Knight, Joey McIntyre, Donnie Wahlberg and Danny Wood. New Kids On The Block (later NKOTB) is a successful boy band of the late 1980s and early 1990s.
