In February 1978, Dolly Parton, Linda Ronstadt, and Emmylou Harris stepped inside the Enactron Truck, a forty-foot mobile recording trailer parked beside the Beverly Hills house Harris shared with her producer husband, Brian Ahern, to cut their first joint album.
Years before they ever faced a studio microphone together, the three singers had discovered their vocal blend sitting cross-legged on the living room floors of Harris’s house and Ronstadt’s Malibu beach home, drinking tea and trading acoustic country songs without a tape machine running. After Ronstadt and Harris flew to Nashville in 1976 to sing “Silver Threads and Golden Needles” and “The Sweetest Gift” on Parton’s syndicated television show *Dolly!*, they decided to turn those living-room harmonies into a full record.
At the time, American country radio stations still followed an unwritten programming rule that rarely placed two female voices back-to-back on the air, treating women in the genre as rivals competing for scarce playlist slots. Inside the Enactron trailer in early 1978, however, the three friends sat together trading verses on the Chordettes’ “Mr. Sandman,” the Carter Family’s “Palms of Victory,” Rodney Crowell’s “Even Cowgirls Get the Blues,” Robbie Robertson’s “Evangeline,” and Parton’s acoustic ballad “My Blue Tears.”
Despite those promising initial tracks, the 1978 project ground to a halt within weeks. Each woman was contracted to a separate corporate record label—RCA Records for Parton, Asylum Records for Ronstadt, and Warner Bros. Records for Harris—leaving entertainment lawyers arguing over who would distribute the album and collect the master royalties.
At the same time, their individual careers were pulling them in three different directions across the map: Ronstadt was headlining rock arenas behind multi-platinum pop albums, Parton was crossing over to mainstream pop radio and preparing for Hollywood film roles like *9 to 5*, and Harris was touring relentlessly with her Hot Band. When the sessions were quietly shelved, music industry trade papers speculated that the three stars had clashed over billing and studio control.
Rather than walking away from the partnership during the nine-year stalemate that followed, the three women salvaged the 1978 recordings and kept singing on one another’s solo projects. In 1979, Harris placed their three-part harmony version of “Even Cowgirls Get the Blues” on her Grammy-winning album *Blue Kentucky Girl*.
Two years later, in 1981, Harris included their 1978 recordings of “Evangeline” and “Mr. Sandman” on her album *Evangeline*, though contractual restrictions prevented Parton and Ronstadt from singing on the single release of “Mr. Sandman,” forcing Harris to re-record all three harmony parts herself for radio. In 1982, Ronstadt released their trio take on Parton’s “My Blue Tears” on her album *Get Closer*.
By late 1985, the legal logjam finally cleared after Parton’s long run with RCA neared its end and Warner Bros. agreed to release a full joint album. Between January and November 1986, Parton, Ronstadt, and Harris reunited at the Complex Studios in West Los Angeles with producer and audio engineer George Massenburg.
Instead of chasing the synthesizer-heavy pop production of the mid-1980s, Massenburg surrounded the singers with acoustic master musicians, including guitarist Albert Lee, multi-instrumentalist David Lindley, mandolin and fiddle player Mark O’Connor, pianist Bill Payne, and bassist Kenny Edwards. Recording live around the microphones, the three women stripped the arrangements back to Appalachian folk, traditional bluegrass, and family harmony.
Parton brought in “Wildflowers,” a personal song rooted in her Sevier County mountain childhood that moved Ronstadt and Harris to tears in the studio, alongside “Rosewood Casket,” an old parlor ballad arranged by her mother, Avie Lee Parton. Even though Parton’s bright, cutting soprano could carry over a full orchestra, she deliberately softened her phrasing at the Complex microphones, matching her breath to Harris’s high folk soprano and Ronstadt’s resonant belt so the three sounded like sisters sharing a single voice.
When *Trio* arrived on March 2, 1987, the album produced four top-ten country singles—including the number-one hit “To Know Him Is to Love Him”—spent five consecutive weeks at number one on the *Billboard* Top Country Albums chart, sold four million copies worldwide, and won the Grammy Award for Best Country Performance by a Duo or Group with Vocal. Walking onto promotional stages in 1987 holding hands and praising one another’s voices, the three women finished the conversation they had started on a California living room floor more than a decade earlier.
