MPB4, formed in Niterói, Rio de Janeiro, in 1965, is a renowned Brazilian vocal and instrumental group celebrated for their exceptional interpretations of samba and Música Popular Brasileira (MPB). The original lineup featured Miltinho, Magro, Aquiles, and Ruy Faria, who remained together for 36 years—a record noted in the Brazilian edition of the Guinness Book of Records. Over the decades, MPB4 has collaborated with esteemed artists like Chico Buarque, Toquinho, and Quarteto em Cy, contributing significantly to Brazil's rich musical heritage. Their harmonious vocals and innovative arrangements have earned them multiple accolades, including the Prêmio da Música Brasileira for Best MPB Group in 1988, 1990, 1996, and 2017.
