In August 2014, NH Media and Nega Network announced the upcoming debut girl group Laboum, who had been training for four years. The group was touted as a sister group to NH Media’s U-KISS and Nega Network’s Brown Eyed Girls.
Laboum released their debut single album Petit Macaron on August 28, 2014, following the release of their music video for title track “Pit-A-Pat” the day before. The song was written by Seo Ji-eum, known for hits such as f(x)’s “Electric Shock” and TaeTiSeo’s “Twinkle”, and composed by Jung Jae-yeob.
On October 24, Laboum announced that they would come back with Petit Macaron DATA PACK, a Petit Macaron re-release with extra digital contents, and a reworking of the track “What About You?”. On October 31, the group held a comeback performance on Music Bank and released the song’s music video, which featured a clockwork doll theme. Petit Macaron DATA PACK was released on November 3.
