Mizuguchi appeared at The Tenth Mosaic in Tokyo on September 22 and 23, 2026, giving a lecture on Rez and joining a roundtable with the original Rez team. The roundtable disclosed unreleased music from the game's production, including an Underworld version that was made but never released.
Tetsuya Mizuguchi's current public profile rests on a single two-day event. Archipel held The Tenth Mosaic, a game culture festival, on September 22 and 23, 2026 at a Tokyo venue. The lineup put Mizuguchi on a Rez 25th anniversary session with techno artist Ken Ishii, alongside talks featuring Kazutaka Kodaka, Masafumi Takada, Keiichiro Toyama, Frederic Raynal, and a Persona 30th anniversary panel. Several talk sessions had sold out before the festival opened.
The Rez session itself produced the substance. Mizuguchi gave a lecture on the game's origins, then joined a roundtable with original director Jun Kobayashi, music producer Masakazu Hiroishi, and Ken Ishii. The discussion turned to music that never shipped. Mizuguchi said an Underworld version of Rez was made but never released, and that Fatboy Slim's track for Stage 2 was pulled roughly three weeks before launch over a sampling concern. Hiroishi said he pitched Rez to Aphex Twin in London and that the artist accepted the job before failing to deliver. Performer Ebizo, also known as sound director Nobuhiko Tanuma, replaced the Fatboy Slim track in two weeks.
Across the two stories, the event is the throughline. The September 4 lineup notice establishes the Rez anniversary session as one item in a broader festival program; the October 5 account of the roundtable shows what that session actually put on the record. Nothing in the coverage describes Mizuguchi's next project or any work beyond Rez and the festival appearance.
