Who Is the Male Voice Behind Rosalía's New Collaboration Teased in Los Angeles?

Rosalía has fans buzzing once again, this time not over a finished single but over a fleeting snippet of unreleased music. During her LUX Tour concert on July 1 at the Kia Forum in Los Angeles, the Spanish superstar gave the crowd a preview of what appears to be a brand-new collaboration — and the internet is trying to figure out exactly who she's working with.

In the fragment that circulated online following the show, a male voice can be heard singing alongside Rosalía. The accent is distinctly Puerto Rican, which immediately narrowed the guessing game for fans combing through the clip for clues. So far, neither Rosalía nor anyone associated with the track has confirmed who the singer is, leaving the identity officially unconfirmed.

"Sun rays, left you with a nice tan color / I wasn't planning on meeting you, but it's a pleasure," the mysterious male voice sings in the preview.

The Leading Theories: Myke Towers and Álvaro Díaz

Two names have dominated fan speculation since the surfaced: Myke Towers and Álvaro Díaz. Both are established Puerto Rican urban artists with recognizable voices, making them natural guesses for a collaboration built around an urban, romantic sound.

Of the two, Díaz has emerged as the fan favorite. Listeners have pointed to the close resemblance between his vocal tone and phrasing and what's heard in the clip, fueling speculation that he could be the mystery collaborator on Rosalía's next release.

Could Tainy Be Behind the Production?

Beyond the identity of the vocalist, fans are also speculating about who produced the track. The name that keeps coming up is Tainy, the Puerto Rican producer known for blending urban music with electronic textures. The theory stems from the sound of the snippet itself, which mixes the emotional pull of a ballad with elements of EDM — a combination that lines up with Tainy's signature style.

If confirmed, this collaboration would mark something of a shift for Rosalía. Her LUX era has been defined largely by a solo, deeply personal artistic vision, with relatively few outside collaborations compared to earlier chapters of her career. A new feature with a Puerto Rican urban artist would represent a notable return to the kind of genre-crossing collaborations that made hits like "Con Altura" and "La Noche de Anoche" massive successes.

What's Next for the LUX Tour

Rosalía is currently ending the North American leg of her LUX Tour. She'll wrap up that portion of the run on July 6 in Oakland, California, before the tour continues on to Latin America. Whether the mystery collaboration gets an official release before then — or whether fans will have to wait even longer for confirmation — remains to be seen.

For now, all eyes (and ears) are on that Kia Forum snippet, as fans continue to dissect every second for clues about who's joining Rosalía on her next musical chapter.

Rosalía's Mystery Song (Previewed in Los Angeles) — English Lyrics

Sun rays, left you with a nice tan color

I wasn't planning on meeting you,

but it's a pleasure,

And I don't know when I'll see you again,

I just don't know

Just stay with me

and watch the sunset, the sunset.

And I don't know when I'll see you again,

I just don't know.

Just stay with me

and watch the sunset, the sunset.
