Avenged Sevenfold released The Stage a few months ago as a surprise, which backfired a bit on sales, but they are not done releasing new tracks yet!
I'll let the band explain it. From the official press release:
Avenged Sevenfold are transforming new album THE STAGE into an evolving body of work by adding a series of new tracks over the course of the coming months.
“We’ve said all along that we want The Stage to be a different and exciting listening experience,” says vocalist M. Shadows. “For us, the idea of turning an album into a living piece of art and adding new installations is really intriguing. It expands the journey.”
That journey begins by crossing the cultural divide with “Malagueña Salerosa,” which is Avenged Sevenfold’s first-ever Spanish-language release. Says guitarist Synyster Gates, “I’ve always loved that song. There have been a few interesting interpretations over the years, including Chingon’s version from the Kill Bill Volume 2 soundtrack. That’s a great example of how a timeless song can be made relevant with a creative modern take. The structure, arrangement and incredible vocal work of their rendition was inspiring.”
Though they originally planned to record the song in both Spanish and English, the band decided to forgo the latter in favor of the traditional version.
“We wanted to do the song justice,” says M. Shadows, “and that meant singing in its original language. It was difficult, but I worked on it for weeks and had a Spanish-speaking friend come over daily to go over pronunciation. I also brought him to the studio to produce the vocals. It was important to me to get it right.”
The band's cover of “Malagueña Salerosa” can be streamed on all major platforms, Apple Music, Spotify, Soundcloud and Google Play. Here are some embeds:
