God bless the music icon, Linda Ronstadt

She is known as the “First Lady of Rock,” and she was a trailblazing singer-songwriter whose unmistakable mezzo-soprano voice could be heard on chart-topping hits like “You’re No Good” and “Blue Bayou.”

Linda Ronstadt, on the other hand, no longer sings, at least not in a way that her fans can hear.

During a recent interview with Maria Shriver, the 76-year-old claimed to be able to sing in her head.

Ronstadt was diagnosed with Parkinson’s disease in 2013 after years of vocal difficulties. She eventually discovered she had progressive supranuclear palsy, a condition similar to Parkinson’s disease.
