Kaethia_ Releases 12-Track Debut Album “One World, One Song” on International Day of Peace

Kaethia_ is not human. Her voice, face and performances are synthetic — generated, not recorded. There is no woman behind them, and there never was.

She was created by António Fontoura and is released on Kaexa Music. Fontoura writes and produces the work and makes the final creative decisions behind every release; Kaethia_ is the artist under whose name it is released. The systems that give her a voice and a face were built at Kaexa Labs. Her releases are declared as synthetic in the credits and metadata supplied to Spotify and other streaming platforms.

Her form is part of the artistic concept rather than a disguise. Kaethia_ has no nationality and no native language, and she is not bound to a single country or physical location. Her voice can move across languages, while her narrative can place her in real cities and landscapes around the world. She does not physically travel: when she appears in real places, the locations are real and her presence there is fictional, functioning as a setting in the same way a real place can function inside a novel.

That freedom is central to One World, One Song. An artist who belongs to no single country can carry a record in which languages and cultures remain distinct while sharing the same home.

Technology is not the subject of the music; it is part of the form through which the work is made. There is an intentional paradox at the center of the album: a synthetic artist imagining a world in which technology repeatedly recedes from everyday life. Kaethia_ exists because of technology; Kæthiar asks what place technology should occupy in our lives.

Across the album, wires, signals, phones, screens, clocks and even technology itself disappear from the foreground, making room for nature, presence, community and direct connection. The contradiction is only apparent. One World, One Song does not reject technology. It imagines technology serving life rather than occupying its center.

“The reason Kaethia_ exists in this form is the work itself,” Fontoura said. “Technology makes her possible, but that does not mean technology should occupy every moment of our lives. Kæthiar is about putting life back in the foreground: people, nature, attention, music and being present with one another.”

The album moves across several languages without treating one language as the definition of belonging. Cuban Flow (feat. Maceo_) features Cuban-American artist Maceo_ and is intentionally led by English with small Spanish touches, reflecting an identity that does not have to prove itself through the language others expect. Il Vento Che Ci Parla (feat. Tazio_) features Italian artist Tazio_ in one of the album’s most intimate moments. Both Maceo_ and Tazio_ are synthetic artists.

The word Kæthiar is intentionally pronounced in different ways across the album. There is no single authoritative pronunciation. In Il Vento Che Ci Parla, Tazio_ and Kaethia_ pronounce it differently, and neither pronunciation corrects the other.

The project’s public principle is simple:

Kaethia_ is a synthetic recording artist released by Kaexa Music. Her songs are built around connection: love, unity, equality, belonging and the idea that different voices can still move as one. Blending contemporary pop with global rhythms and a warm, uplifting sound, she creates music intended to feel immediate, universal and shared. Her debut single, Same Light, Same Love, was released September 4, 2026. One World, One Song is her 12-track debut album.

Kaexa Music is the music label within Kaexa, releasing artist projects developed across the company’s creative and technological ecosystem. Kaethia_ is released on Kaexa Music, with the systems supporting her synthetic voice and visual performances developed at Kaexa Labs.
