Legendary Korean hip-hop duo DEUX will release their fourth full-length album on November 21, 2026 — their first in 31 years — featuring the voice of late member Kim Sung-jae recreated with AI technology, agency Wide Company announced on November 10.
According to SPOTV News, the album is titled “4th Deux,” and it arrives nearly 31 years after the duo’s third album, “Force Deux,” released in 1995. The comeback was unveiled at a pre-listening party held on November 7 at the Bolero Club in Itaewon, Seoul, hosted with YouTube channel df, where industry figures and fans heard the record first.
The album carries two title tracks. The first, “The Future,” was introduced with a screening of its music video and a behind-the-scenes look at its production by surviving member Lee Hyun-do, who served as executive producer. The second, “I Want You,” features hip-hop duo Dynamic Duo, who also performed at the party, followed by an after-party set from DJ Nodo.
What sets the project apart is how “The Future” was made. The track combines AI vocal filter technology from SoriSori AI with 3D pre-visualization and motion tracking from The Ape Squad, recreating Kim Sung-jae’s voice and performance. The production was supported by South Korea’s Ministry of Culture, Sports and Tourism and the Korea Creative Content Agency.
Lee Hyun-do said he thought hard about how to face a different kind of future as DEUX than the one he explored on his solo album, and described the song as his answer to what DEUX’s evolved new jack swing would sound like today. He also said he will share part of the performer’s neighboring rights income from the project with Kim Sung-jae’s bereaved family, a gesture honoring his late bandmate.
DEUX debuted in 1993 and became one of the defining acts of Korean dance music and early K-pop, scoring hits with “Turn Around and Look at Me,” “We,” and “In the Summer.” The duo announced their disbandment in 1995, and Kim Sung-jae launched a solo career the same year. He was found dead in a Seoul hotel on November 20, 1995, the day after performing the first stage of his solo debut track “Let’s Talk.” He was 24.
A live video of the party will be released on df’s YouTube channel at 6 p.m. on November 20 — the 31st anniversary of Kim Sung-jae’s death — one day before the album arrives.
