Marcos Kostenbader Valle (born in Rio de Janeiro) is a Brazilian singer, instrumentalist, songwriter and record producer. He has produced works in many musical styles, including bossa nova, samba, and fusions of rock, soul, jazz, and dance music with Brazilian styles.
Valle's talent was evident from his high school years, which coincided with the explosion of the bossa nova movement in Rio. His classmates included future legends such as Edu Lobo and Dori Caymmi, and his composition Sonho de Maria was included on the Avanco album by the influential Tamba Trio in 1963. With his brother Paulo Sergio Valle as his lyricist, he had already built an impressive portfolio of songs, prompting Odeon Records (a subsidiary of EMI) to sign him as a singer. His debut album Samba Demais, was released in April 1964. His reputation quickly spread, and his fellow musicians (including Wilson Simonal, Elis Regina, and Nara Leão) lined up to record his songs. A second album, O Compositor e o Cantor, followed in 1965, and featured what would become his most recognisable song, Samba De Verão – known in English as So Nice (Summer Samba) – along with other hits such as Deus Brasileiro, Gente, and A Resposta.
Nineteen sixty-six brought Valle's first trip to the United States, where he and his then-wife Anamaria briefly teamed up with Sérgio Mendes in an early version of what would later become Brasil '66. The threat of being drafted and sent to Vietnam caused Valle to return quickly to Brazil, although the following year saw him back to the United States and enjoying some success, including the release of his U.S. debut album, Braziliance!, on Warner Bros. Records, and several appearances on the Andy Williams TV show. Following session work on Verve Records releases by compatriots Walter Wanderley and Astrud Gilberto, the label released Valle's Samba '68 featuring English-language versions of songs from his earlier Brazilian releases.
