Spectral Works is a division of Ethereal Sound Works, created in 2026 to support the digital releases of Os Vultos, a drone, noise, and experimental music project. The label is planned as a five‑year initiative dedicated to documenting and expanding the band’s sonic output.
Initially conceived with a primary focus on the releases of Os Vultos, the project evolved in less than two weeks to broaden its scope. It was subsequently opened to include additional bands, projects, and artists. As a result, Buraco Negro became the second band to join Spectral Works.
It is anticipated that additional projects will follow, all aligned with the purpose of supporting their respective releases.
