Linda Ronstadt has earned the admiration of millions of fans since she launched her career in the 1960s — Dolly Parton among them. “Linda could literally sing anything,” says Parton in a new trailer for “Linda Ronstadt: The Sound of My Voice.” The upcoming documentary pays tribute to the genre-hopping trailblazer.

Interviewee after interviewee emphasizes Ronstadt’s talent, star power, and determination. The latter came in especially handy given the sexist climate she worked in. “Rock ‘n’ roll culture seems to be dominated by hostility against women,” Ronstadt says in the spot. The Stone Poneys singer became the first woman to break a number of records, and we’re told that “people didn’t notice the difficulty of being a woman trailblazing and having the success of Mick Jagger.”

“Linda Ronstadt: The Sound of My Voice” uses “deep-cut archival footage, and Ronstadt’s own astute recollections, to celebrate an artist whose desire to do justice to the songs that touched her soul made generations of fans fall in love with her — and with the sound of her voice,” according to the doc’s official synopsis. The film opens September 6.
