Boy band ZeroBaseOne, also known as ZB1, performs lead track “In Bloom” during its debut showcase at the Yes24 Live Hall in eastern Seoul’s Gwangjin District on Monday. The band was formed with the top nine finalists of Mnet’s hit audition show “Boys Planet” which ended in April. Before even making its official debut, ZeroBaseOne sold over a million copies of its first EP “Youth in the Shade” in pre-orders, setting a new record for a debuting K-pop act. It is the first K-pop artist to reach million-seller status with its first release. [WAKEONE] #ZEROBASEONE #ZB1 #debut Credits: WAKEONE
