Grupo Frontera is an American regional Mexican band from Edinburg, Texas. The band consists of Adelaido "Payo" Solís III (vocals, bajo quinto), Juan Javier Cantú (vocals, accordion), Julian Peña Jr. (congas), Alberto "Beto" Acosta (bajo quinto), Carlos Guerrero (drums), and Carlos Zamora (bass guitar). By May 2023, the band achieved its first top five hit on the Billboard Hot 100 with the Bad Bunny collaboration "Un x100to". In response to this, Grupo Frontera announced a 23-date tour to begin in mid-2023. An article by Billboard considered the band's success integral in the breakthrough of the regional Mexican genre. The band achieved fame through their norteño cumbias, but upon the release of their full-length debut album in August 2023, El Comienzo, they proved they could delve into other regional Mexican styles, as well as outside the genre.
