KF was born in Paraná and began making music in 2018, recording his first songs on a phone microphone and posting them only on YouTube. In 2019 he started releasing on streaming platforms and stood out with songs that explore fantasy universes, according to his official Spotify bio.

The centre of that universe is Velho Oeste Town, a fictional town he created, where the imagery of the Old West is reimagined inside sung stories. The repertoire includes tracks such as O Conto de Maria, with Anny Koch and Nanasai; João e Maria, with Kamaitachi, Koda and Bruno Bsv; Velho Oeste Town; Jack Mack Flack; Sabrina, with Anny Koch; O dia que o Diabo andou sobre a Terra; and Jack Vigarista 2, with Koda.

The work grew in chapters. O Conto de Maria came out on April 16, 2021, followed by Acústico Histórias in 2022 and O Conto de Maria 2 on October 4, 2024. On July 18, 2025 came Para alguém, algum dia no futuro, and on May 8, 2026 the album Daqui a incontáveis eras, ainda estarei aqui, with 21 tracks and 1 hour 21 minutes, plus the single O Fim da Velho Oeste Town on September 18, 2026 and Lugar Escuro, with Akami, on October 16, 2026.

Reach is not what the narrative depends on. What sustains the project is the continuity of the story, a proposition that asks for an audience willing to follow chapters rather than isolated tracks. Releases carry a label credit in the artist's own name, with distribution through Shake Music according to the streaming pages.

The bio itself acknowledges a recent step back: the artist describes himself as somewhat removed from the music world, still sharing compositions as a refuge for those who want to escape reality. For newcomers, the clearest order is to start with O Conto de Maria, move through O Conto de Maria 2 and finish with the 2026 album, when the imaginary town finally reaches the scale of a novel.
