Born as Diana Reches, Diane Denoir made her debut as a singer in 1966, backed by Eduardo Mateo on guitar. Influenced by Françoise Hardy and Astrud Gilberto, along with her own unique style, she performed a special blend of chanson française, bossa nova (sung in Portuguese, English, and French), and jazz. By then, Mateo was already a well-known guitarist in the Uruguayan music scene and a sought-after arranger. He was also beginning to establish himself as an incredible songwriter, connecting different musical universes in unique ways. The two formed a fruitful artistic partnership that lasted until the early seventies. This album, originally released in 1998 on CD, is a compilation of various unreleased recordings from different sources (concerts, radio and TV recordings, homemade tapes) made between 1966 and 1968. It is a unique document that showcases their incredible musicianship and creativity in their early years. The duo swings from bossa nova classics like "The Girl from Ipanema" to the rhythm and blues of "Fever," including chanson française standards like "Le lendemain" and "La Dernière Valse." The album also features earlier versions of the three best-known Mateo songs performed by Diane: "Y hoy te vi," "Esa tristeza," and "Mejor me voy," all of which were inspired by Diane. Inéditas unveils a new dimension of South American music from an unforgettable era.
