BTS member Suga has returned as Agust D.

At 1 p.m. on the 21st (KST), Suga released his first official solo album, "D-Day," on major music sites. The music video for the title track "Liberation" was also released on the same day.

"Liberation" captures the theme running throughout the album, characterized by its ambiguous expressions. The use of the traditional Korean instrument 'haegeum' adds to the meaning of "lifting the ban" (解禁).

The music video is also laden with significance. Suga plays dual roles, portraying contrasting characters and metaphorically expressing a farewell from the self-confining subject.

The lyrics focusing on the "self" are also captivating: "Liberation from the forbidden things / It's comfortable when I close my eyes, everything is obvious / Don't get swept away in the tsunami of information," posing a question through the song.

"D-Day" is the final installment of the Agust D trilogy. It is the finale following the mixtapes "Agust D" (2016) and "D-2" (2020), which Suga released under his stage name.

The album features a total of 10 tracks. In addition to "Liberation," Suga included "D-Day," "Amygdala," "SDL," "Polar Night," and "Life Goes On."

Collaborations with numerous musicians are featured. "People Part 2" is with singer IU, and "HUH?!" is with J-Hope. Suga also collaborated with the late Ryuichi Sakamoto, The Rose's Kim Woo-sung, and Snooze.

It's no exaggeration to say that Suga poured his musical capabilities into the album. He led the entire process, from lyric writing, composing, album planning, and structure to producing.

A documentary is also set to be unveiled. Disney+ will release "SUGA: Road to D-DAY" at 11 p.m. on the same day, revealing the process of creating the new album.

Meanwhile, Suga is gearing up for a world tour. Starting with the UBS Arena at Belmont Park in New York on the 26th and 27th, he will meet fans, known as ARMY, from all around the world.
