One of the pioneers of the 90s boy band craze worldwide, New Kids on the Block have sold more than 80 million records worldwide. Helming from Boston, the group was a massive music phenomenon sending teens into a frenzy everywhere they went. They split apart in 1994 and wouldn't reunite again until 2008. Since then, they've made countless nostalgic appearances, have released new music off and on and toured together. Most recently, they appeared on "Dick Clark's Rockin Eve" on New Years Eve in Times Square and announced they would be touring in 2019 with other 80s and 90s superstars like Deborah Gibson and Tiffany.
