Sérgio Santos Mendes (born February 11, 1941 in Niteroi, Brazil) is a Brazilian musician. He has released over thirty-five albums, and plays bossa nova heavily crossed with jazz and funk.
Mendes is married to Gracinha Leporace who regularly performs vocals for her husband and can also be heard on his 2006 version of the Jorge Ben Jor song "Mas Que Nada" with The Black Eyed Peas.
The child of a physician in Niterói, Brazil, Mendes attended the local conservatory with hopes of becoming a classical pianist. As his interest in jazz grew, he started playing in nightclubs in the late-1950s just as bossa nova, a jazz-inflected derivative of samba, was emerging. Mendes played with Antonio Carlos Jobim (regarded as a mentor) and many U.S. jazz musicians who toured Brazil.
Mendes formed the Sexteto Bossa Rio and recorded Dance Moderno in 1961. Touring Europe and the United States, Mendes recorded albums with Cannonball Adderley and Herbie Mann and played Carnegie Hall. Mendes moved to the U.S. in 1964 and cut two albums under the Sergio Mendes & Brasil '65 group name with Capitol Records and Atlantic Records.
