I bought a download copy of The Complete Trio Collection, a remastered edition of Dolly Parton, Emmylou Harris, and Linda Ronstadt’s albums Trio, Trio 2, and a whole bunch of unreleased tracks.
The vocals and harmonies are sublime; all three vocalists were at the peak of their powers when these were recorded.
Here’s Do I Ever Cross Your Mind, from Trio 2 and an unreleased version that has a lead by Parton.
