The Complete Trio Collection

The Complete Trio Collection is compilation album by American singer-songwriters Dolly Parton, Emmylou Harris and Linda Ronstadt. It brings together newly remastered versions of their two award-winning albums, 1987's Trio and 1999's Trio II, with a third disc compiling 20 alternate takes and unreleased material. It was released worldwide on September 9, 2016, by Rhino Entertainment. A stand-alone version of the third disc, titled Farther Along, was released separately on vinyl.

Despite being touted as "complete", the set is missing three recordings that feature the trio. Those three tracks are:

• "Light of the Stable" – recorded and released as a single in 1975 featuring additional harmony vocals from Neil Young, it was also included on Harris' 1979 album of the same name.
• "Evangeline" – recorded in 1978 and featured on Harris' 1981 album of the same name, along with "Mr. Sandman", which is included on this set.
• "Palms of Victory" – recorded in 1978, this track went unreleased until Harris' 2007 compilation album Songbird: Rare Tracks and Forgotten Gems, along with "Softly and Tenderly", which does appear on this set.

Additionally, Parton and Ronstadt both provided harmony vocals on various tracks throughout Harris' 1985 album The Ballad of Sally Rose. The three also performed together on TV in the 1970s.
