Lee Soo-man Returns with A2O Soul and A2O Lite, Unveiling 4DGS Technology
After a three‑year hiatus imposed by a non‑compete agreement with his former label SM Entertainment, legendary K‑pop producer Lee Soo‑man made his highly anticipated comeback in October 2024. The debut showcase of his new agency, A2O Entertainment, introduced two fresh acts — A2O Soul (a 15‑member boy band) and A2O Lite (a nine‑member girl band) — alongside a cutting‑edge visual technology called 4DGS, short for “four‑dimensional Gaussian splatting.” The event, held at Kintex in Goyang, Gyeonggi Province, signaled Lee’s ambition to push K‑pop beyond music into immersive, interactive experiences.
The Debut Showcase at Kintex
Titled “Welcome to Soulite From A2O Soul A2O Lite,” the press event broke from the traditional K‑pop debut format. Rather than delivering spoken remarks, the newly formed groups performed their debut singles in silence, letting the music and choreography speak for themselves. Lee Soo‑man took the stage to outline his vision, emphasizing that technological innovation must always serve the song.
The audience witnessed a joint dance performance, followed by A2O Lite’s bass‑driven track “Neon” — described by the agency as “Zalpha pop” — and A2O Soul’s synth‑infused “Superstar,” labeled “New Synthwave.” Both songs were made available on streaming platforms the next day.
4DGS: A New Dimension in K‑pop Visuals
Lee Soo‑man introduced 4DGS as the next evolutionary step after his earlier “Matrix Camera System,” which had created the illusion of a camera circling a suspended idol in music videos for acts such as Girls’ Generation and SHINee. 4DGS captures a performance in 360‑degree video, allowing viewers equipped with a VR headset to move freely within the recorded space and observe the idols from any angle.
During a pre‑showcase demonstration, journalists wearing headsets walked among the performers, experiencing the sensation of standing inside the formation and looking out from behind the members. Lee described the technology as potentially “the ultimate form of the camera as a recording device,” suggesting it could redefine how fans consume K‑pop content.
Meet the Groups: A2O Soul and A2O Lite
A2O Soul blends Korean, Japanese, Chinese, and Thai talent, with members such as Moon, Seoha, Hansung, See‑one, Lucien (Korea/USA), Sora, Gaku, Sono (Japan), Teo, Jun, Tai, Zai, Ayden, Zet (China), and Alure (Thailand). Their concept centers on traveling from the resource‑rich planet Soulite to Earth in search of “soul” — emotions like happiness, love, and passion.
A2O Lite, meanwhile, emphasizes individual “unique colors” shaped by each member’s memories and emotions, which blend to create new hues. The lineup includes Young, Vora, Ayune (Korea), Himeki (Japan), Xili, Merci, Aijing (China), Rada (Thailand), and Oa (dual U.S./Japanese citizenship).
Both groups are positioned within A2O’s fictional “ACE” (A2O Cosmic Epic) universe, a narrative framework that allows for future subunits with varying member combinations.
AI‑Powered Fan Interaction: Blooming Talk
Alongside the musical and visual innovations, Lee unveiled Blooming Talk, an AI‑driven platform enabling fans to communicate with the idols and interact with AI avatars of the group members. The system answers the recurring question Lee says he has heard throughout his career: “What’s the difference?” By focusing first on emotional resonance — “This is good” — Lee hopes technology will enhance, not overshadow, the core musical experience.
Industry Context and Future Prospects
Lee Soo‑man’s return arrives at a time when K‑pop continues to dominate global markets, with groups experimenting with metaverse concerts, AI-generated music, and immersive video formats. His departure from SM Entertainment in 2023, followed by the sale of his shares to HYBE and the subsequent establishment of A2O Entertainment in 2024, marked one of the most high‑profile reshuffles in the industry.
As of September 2025, A2O Soul and A2O Lite have maintained a steady promotional cycle, appearing on music shows and releasing behind‑the‑scenes content that highlights the 4DGS experience. No additional major technology updates or new subunit announcements have been disclosed by the agency, but the foundation laid at the October 2024 showcase suggests a continued focus on blending artistic performance with immersive media.
Whether 4DGS becomes a widespread standard or remains a niche showcase piece, Lee Soo‑man’s latest venture underscores the ongoing experiment at the intersection of K‑pop music, visual technology, and fan engagement — a space where the next evolution of the genre may be forged.
