Baca was born in the black coastal barrio of Chorrillos, outside Lima, where descendants of slaves have lived since the days of the Spanish empire. Her family was interested in music; her father played the guitar, while her mother was a dancer, and she grew up listening to Cuban musicians like Pérez Prado and Beny Moré. Baca's singing first came to public attention when she was a student. She formed an experimental group combining poetry and song, and started performing after receiving grants from Peru's Institute of Modern Art and the National Institute of Peruvian Culture. She attracted the attention of the composer and singer Chabuca Granda, who became her mentor. Granda encouraged Baca to record, but a 1983 record deal fell apart upon Granda's death. Baca then turned her attention to researching the Afro-Peruvian tradition. With her husband she founded the Instituto Negrocontinuo (Black Continuum) in Lima, which is dedicated to preserving Afro-Peruvian culture. ~ Spencer Harrington, All Music Guide
