Upcoming four member girl group 'Blady', who previously earned headlines for being praised by Shinsadong Tiger, has made their official debut with the release of their digital single, "Spark Spark"! This girls' official title track, "Crazy Day", won't be released until May 27th, so this single album is an introductory album to music fans.  "Spark Spark" features a retro sound that's easy to follow along with. CEO Kim Tae An of SY6 Entertainment commented, "The girls contracted for a CF with KT Olle On Air prior to their debut and are already preparing to advance into Vietnam, Japan, and China. Through the praise of Shinsadong Tiger, they're one of the likely candidates to win a rookie award at this year's year-end ceremonies." The girls will be holding their debut showcase in Gwanghwamun on May 17th. If you haven't already, be sure to check out their individual profiles here. Source + Photo: TV Report via Naver
