The titular seven members were South Koreans JB and Junior (formerly of the J.J. Project), Youngjae, and Yugyeom; American-born Taiwanese, Mark; Jackson from Hong Kong; and BamBam from Thailand. The latter four joined the group after competing on the South Korean reality show, Who Is Next: WIN. Typical of other multi-member K-Pop groups, the boy band employed a mixture of rapping, R&B-inflected crooning, and layered harmonies, as well as expertly synchronized dance moves. Their first EP, Got It?, was released in early 2014 and was quickly followed up six months later with Got Love. Their first full-length, Identify, was released in late 2014 and included the hit "Stop Stop It." Atypical of the fast-moving, ephemeral nature of the K-Pop industry, they wouldn't release their next EP until a full eight months later in July 2015. That "mini album," Just Right, was immediately followed with their second Billboard World chart-topper, Mad, a six-song ride of futuristic techno-R&B, slinky pop, and catchy hooks. ~ Neil Z. Yeung
