One of the highlights of Rosalía’s rapid ascent from alt-flamenco niche figure to world-conquering pop icon was her appearance on the Colombian reggaetón superstar J Balvin’s 2018 album Vibras. With her voice dancing over Balvin’s irresistible alto croon, “Brillo,” which she co-wrote with Balvin’s longtime producer Sky, showed a new contemporary whimsy to her singing. Far from the flamenco standards of her debut or the weighty historical references of her breakthrough album El Mal Querer, it was a bubbly look at digital flirtation.

Like “Brillo,” the singers’ new collaboration “Con Altura” is meant to be playful, but this time, instead of a ballad, it’s a straight-up reggaeton banger, courtesy of a snapping dembow beat by the Canadian producer Frank Dukes and Spain’s El Guincho, Rosalía’s collaborator on El Mal Querer. Lyrically, it’s a lighthearted mix of boastful tropes: There are nods to the singer’s flamenco roots, references to jewels and flashy cars, and even a riff on living fast and dying young (“Vivo rápido y no tengo cura/Iré joven pa’ la sepultura”). El Guincho gets a few lines in too, but his choruses are mainly there to set up Balvin, who sidles into the frame with his typical swagger; not since Gang Starr’s Guru has a rapper had such an appealingly sandpapery voice. If anything, the contrast between the two is even more pronounced here than it was on “Brillo,” where Balvin’s voice was cocooned in Auto-Tune. Her coo and his rasp make perfect complements. Over and done within less than three minutes, it’s a high-flying trifle of a song whose video and title (“Con Altura” is a reference to great heights) show both artists at the top of their game.
