La Chica Belleville is a music project created by Franco-Venezuelan singer songwriter Sophie Fustec. If magic realism had a soundtrack this could be it: with her hypnotic vocals, Debussy-inspired piano and adept sampling of Latin American percussion she builds "a collage" of colours and moods to achieve a state of trance. Just ahead of the release of her debut album Cambio (Change) she talks to Alison Hird about being saved by music and - trying, however humbly, to do the same for people suffering in Venezuela.
