Discography of 24K

K-pop boy band 24K were among high-profile South Koreans blacklisted under the administrations of Lee Myung-bak and Park Geun-Hye, both jailed former presidents. Sources within Choeun Entertainment stated that the agency believed 24K was blacklisted after singing the theme song for Moon Jae-in’s 2012 election campaign. The blacklisting had an impact on the career of the boy band, making it impossible for 24K members to appear on some South Korean TV shows. The group underwent several line-up changes during the blacklisting period and focused on overseas activities.

Consequently, 24K was able to release the following mini-albums; Hurry Up (2012), U R So Cute (2013), Super Fly (2015), Addiction (2017), and Bonnie N Clyde (2018). The group’s only studio album, The Real One was released in October 2016. Their first world tour, “Still With 24U” took place between 2017 and 2018. They also did their First Encore Tour “Still With 24U, The Encore” within the same years. Before the tours, their First European concert was in Warsaw, Poland on January 23, 2016.
