Coin Jackson was a groundbreaking South Korean girl group that defied traditional K-pop norms by specializing in hip hop acapella music. Created by PPP Entertainment, they quickly gained recognition as "Asia's first hip hop acapella group." The group's name, an abbreviation for "Korea in Michael Jackson," symbolized their aspirations for global success akin to the legendary artist. Debuting on Valentine's Day in 2011 with the powerful track "Beginning," Coin Jackson unfortunately faced challenges leading to the departure of most members and ultimately disbanding later that year.
