Dolly Parton, Linda Ronstadt and Emmylou Harris teamed up in 1987 to form a supergroup and record the award-winning album, Trio. The threesome followed that collection up with 1999’s Trio II. The two albums combined to sell more than 5 millions copies and win three Grammys. And now there is more good news for fans of Dolly, Linda and Emmylou.

A newly remastered three-CD set, The Complete Trio Collection, will drop on Sept. 9. The new collection will feature remastered versions of Trio and Trio II as well as a bonus disc that contains rare and unreleased music, including an alternate take of “Wildflowers,” a tune that Dolly penned and the threesome recorded on Trio.

Check out the alternate recording from 1986 that is available on The Complete Trio Collection.
