Oniria have released the digital single and official visualiser “Esto Es Halloween” on 30 October. The Spanish symphonic gothic metal band’s version of Danny Elfman’s song from Tim Burton’s film “Pesadilla Antes De Navidad” features guest vocals from Patxi Mira, singer of Khelleden, and Marcos Aladro.
The visualiser is now live on YouTube. Mario Hernández created it, as well as the single artwork, and composed and arranged the orchestral parts for the recording. Hernández also produced the track, while he and Mira mixed and mastered it. Mira recorded the vocals at Alter Studios.
The release follows our earlier report on the planned premiere, which placed the song outside Oniria’s planned debut-album campaign. The band’s first album is due in early 2027, with further previews expected to be announced later.
Carolina Viedma leads the release
Carolina Viedma sings in Oniria and has been part of the Madrid band since it formed in 2026. She performs on “Esto Es Halloween” alongside Hernández on bass, Eneko Díaz on guitar and Diego Fernández on drums. The group released the singles “Al despertar” and “Vivir en ti” earlier in 2026.
The single is available through digital platforms, while Oniria’s current line-up remains Viedma, Hernández, Díaz and Fernández.
