Bonello seized on the idea of making a cinematic tribute to Ingrid Caven when he first heard her sing at the Cité de la Musique in Paris, but the portrait he eventually made finds her exploring a more expansive range of performance styles and moods. A former member of R.W. Fassbinder’s cinematic troupe—the two were married for a brief stretch in the 1970s—and the ostensible subject of a fictional biography by Jean-Jacques Schuhl, Caven spends Bonello’s movie singing a rich repertoire of songs, some of them traditional ballads, others non-verbal, and still others verging on abstract performance art. Ingrid Caven: Music and Voice is a showcase for a truly sui generis musician—a sort of cabaret singer for the 21st century—and a respectful tribute to one artist from another.
