One of life’s greatest tragedies is that Linda Ronstadt’s singing voice—a once-in-a-millennium instrument of good in this wicked world—has been silenced due to her struggles with Parkinson’s. That's made clear by directors Rob Epstein and Jeffrey Friedman in Linda Ronstadt: The Sound of My Voice, largely thanks to the numerous clips of Ronstadt's performances they squeeze into the documentary's 95 minutes. What they don’t include is enough of Ronstadt’s speaking voice, preferring to let talking heads tell the bulk of the 73-year-old artist’s story. The fact those dull talking heads are mostly dudes—including Ronstadt's skeevy ex, J.D. Souther—only makes her silence feel that much louder. The only person who gets it right is Emmylou Harris, who's reduced to tears when she’s reminded her friend can’t ever sing again. And when you hear Ronstadt performing everything from Buddy Holly to Gilbert and Sullivan, chances are you’ll cry too.
