His Debut with MBLAQ


G.O raised his popularity as a K-Pop idol when he debuted as an MBLAQ member. The group officially debuted under J. Tune Entertainment in October 2019 and performed several singles from their debut album titled Just BLAQ. He was in charge of the main vocalist position and used G.O as his stage name. For their music, MBLAQ emphasized the K-Pop, R&B, and EDM genres.

“Oh Yeah” is marked as their debut single and it is also included in the Just BLAQ album, and the single was welcomed by people warmly. For their debut stage, it took place in the music show M! COUNTDOWN. Since their first appearance, people have been amazed by them and consider them to be one of the ‘it guys’ in the K-Pop music industry.


MBLAQ’s G.O also participated in a bunch of MBLAQ songs. One of the singles titled “Can’t Come Back” was composed by him, and it was included in the BLAQ Style – 3D Edition album in 2011 and successfully entered top rank on several charts. A year later, G.O and another MBLAQ groupmate, Mir, released a single titled “Wild” in the group’s Asia tour.

MBLAQ Disbandment Rumor


Although MBLAQ have been steadily building up their popularity ever since their debut, they have also faced an unpleasant piece of rumors due to their uncertain circumstances. The group’s latest project was the single “Mirror” in 2015 with only three members since Lee Joon and Thunder decided to leave the group in 2014.

After that, there is no further project or any schedule related to MBLAQ. It felt like the group has been MIA (missing in action) because there was no official statement whether they would be on a hiatus or disband after all. Their agency also didn’t explain anything and remained silent.


MBLAQ’s G.O finally spoke up about all of those non-sense rumors regarding MBLAQ and explained everything through a letter. It was revealed that G.O was trying to set up a fan meeting, however, the agency didn’t make any move or help him.

Since he, Mir, and Seungho weren’t involved in a contract with the label, it also made their agency practically ‘gone’ in terms of responsibilities for the artists’ activities. So, the three remaining members decided to each take their own path. Still, they kept in touch with each other and kept supporting each other.
