Beto Guedes had several hits with his personal blend of Beatles-influenced pop music, a pinch of on-the-road countercultural ideas, and ecology. Among them were "Amor de Índio," "Lumiar" (with Ronaldo Bastos), "O Medo de Amar é o Medo de Ser Livre" (with Fernando Brant), "Luz e Mistério" (with Caetano Veloso), "O Sal da Terra," and "Canção do Novo Mundo" (with Ronaldo Bastos). His songs have been recorded by artists like Elis Regina, Milton Nascimento, and Simone. His first group, formed in his teens with Lô Borges, was called the Beevers. In 1970, he participated in the VFIC with "Feira Moderna" (with Fernando Brant), which was recorded by the Som Imaginário. A member of the group of composers and musicians from Minas Gerais called the Clube da Esquina, he participated in Milton Nascimento's albums Clube da Esquina and Minas. In 1973, he participated in the collective project Beto Guedes, Danilo Caymmi, Novelli e Toninho Horta. His first solo album came out in 1977, A Página do Relâmpago Elétrico, followed by nine others until 1999.
