Eslabon Armado was formed in 2017 by brothers Pedro Tovar (lead vocals), Brian Tovar (bass), and their friend Gabriel Hidalgo (acoustic guitar). Ulises González replaced Hildago in 2021 as acoustic guitarist, and Damian Pacheco (requinto guitar) joined the trio the next year. Based in California, Eslabon Armado's music is a fusion of traditional Mexican music with modern trap and urban pop, creating a unique sound that has gained them a large following.

Peso Pluma joins Eslabon Armado on this song. Peso Pluma is a rapper/singer from Guadalajara, Mexico, who first released music in 2020. In Portuguese, the term "Peso-pluma" translates to "lightweight" or "featherweight," which aptly captures the lively and danceable rhythms in his songs.

"Ella Baila Sola" translates to "She Dances Alone." In the song, Pedro Tovar and Peso Pluma fall head over heels for a girl they've seen dancing. She's got a perfect body and stunning eyes he can't resist. Peso doesn't waste any time and boldly tells her she's gonna be his girl in a few days. She's surprised, but she's feelin' it. Here's how the first verse translated into English goes: Hey bro, what do you think of that girl? The one dancing all alone, she's fine as hell She knows she's hot, everyone's watchin' her move I walk up and drop some smooth lines, we drink and flirt without a care I tell her straight up, 'I'm gonna make you mine in just a few days' She thinks I'm crazy but likes the way I play No other guy can do it like me
