The band previously declared their intentions not to leave The Stage as it first appeared when released back in October. In fact, today’s new addition is what the group envision as on ongoing process of fresh addendums for the album.

“We’ve said all along that we want The Stage to be a different and exciting listening experience,” says A7X 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.”

“Malagueña Salerosa” (also known as “La Malagueña”) is Avenged Sevenfold’s first-ever Spanish-language release. As seen below, A7X have also shared a behind-the-scenes studio video to accompany the creative cover track.

The new song, recorded with producer Joe Barresi and featuring horn players Rachel Tate Herrmann and Sarah Bauza, was poured over by vocalist Shadows to get the Spanish vocals right. The musician says he even enlisted the help of a friend to hone in the original folk song’s lyrical nuances.

“We wanted to do the song justice,” adds Shadows, “and that meant singing in its original language. … 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.”

“Malagueña Salerosa” has been covered by numerous artists over the years, as explained by A7X guitarist Synyster Gates.

“I’ve always loved [the] song,” says Gates. “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.”

Avenged Sevenfold are currently on a stadium tour with Metallica—check out the list of cities and dates after the video.
