Diego & Arnaldo and Zé Neto & Cristiano are Brazilian sertanejo duos active in the contemporary popular music scene. Diego & Arnaldo are known for their work within the sertanejo universitário and country-influenced styles that have been prominent in Brazil since the 2000s, blending acoustic guitars, melodic vocal harmonies and romantic or rural-themed lyrics. Zé Neto & Cristiano emerged as a successful sertanejo pair in the 2010s, similarly combining elements of traditional sertanejo, pop and romantic balladry, often featuring polished production, emotive lead vocals and themes of love and everyday life. Both duos are examples of Brazil’s modern sertanejo movement that brought rural-rooted song forms into mainstream popular music.
