I don't know of a better sound when two or more voices come together in harmony. The harmonies Dolly Parton, Emmylou Harris, and Linda Ronstadt sang are pure joy to listen to. The 'Trio' released two critically acclaimed albums, one in 1987 and another in 1999. Now, according to Parton, a third disc that will be comprised of never-before released tracks will be coming out later this year.

The ladies first appeared together on Dolly's late 70's variety show "Dolly" and here they are performing my favorite, "Apple Jack".

As of 2013, Parkinson's Disease has taken away Ronstadt's ability to sing and the ladies may never perform together again, alas, I can't wait to hear all of their undiscovered harmonies.
