When Pedro heard Ariel Camacho's "El Karma" as a kid, he asked his dad to teach him guitar; by his early teens he and Brian had formed Eslabon Armado with friend Gabriel Hidalgo, singing plainspoken heartbreak songs over just bajo sexto, requinto, and bass. Their unadorned, confessional style — sometimes called "sad sierreño" — turned them into one of regional Mexican music's biggest crossover acts, culminating in 2023's "Ella Baila Sola" with Peso Pluma, the first regional Mexican song to crack the Billboard Hot 100's top ten. Pedro remains the group's songwriter and vocalist, now joined by Brian and guitarist Damian Pacheco.
Pedro Tovar has said hearing Camacho's "El Karma" on Spanish radio as a kid is the reason he picked up a guitar at all: "When I listened to Ariel Camacho I was like, I want to do this — I want to pick up a guitar, I want to play." He's called Camacho's impact on regional Mexican music so foundational that "none of these new artists will be who they are right now" without him — the direct source of Eslabon Armado's stripped-down, guitar-only "sad sierreño" template.
listen forSet "El Karma" beside "Con Tus Besos": both strip the arrangement down to interlocking twelve-string guitars and a walking bass under a plain, unhurried vocal, letting a heartbreak lyric sit in open space rather than building to a big chorus.
Pedro Tovar has told Billboard that going to see Los Tucanes de Tijuana and Legado 7 in concert with his family was what convinced him to chase music professionally, his father telling him "one day that will be you up there." Los Tucanes helped keep the corrido's narrative backbone — verses that tell a specific story beat by beat — alive into the modern era, a structure Eslabon Armado carries into their own corridos tumbados material.
listen forLine up "La Chona" with "Jugaste y Sufrí": both move through a song like a story being told in order, verse by verse, building the narrative detail-first rather than leaning on a repeated hook.
"Sad sierreño" is a genre built on a move Solís spent two decades making the commercial gospel of Mexican radio with Los Bukis: an unguarded breakup lyric sung plainly over a pretty, unhurried melody, with the tune's prettiness doing nothing to soften the sadness of the words. Eslabon Armado swap Los Bukis's strings and horns for bare guitars, but the emotional architecture — plainspoken confession, melody first — traces back to that grupera-ballad tradition.
listen forCompare "Tu Cárcel" with "Te Quiero a Ti": both let a narrator plainly admit he can't get over someone over a warm, mid-tempo melody that stays gentle even as the lyric turns bleak.
