In just six years, singer Patsy Cline forever changed the course of country music. Solidifying her career with classics such as "Crazy," "Walkin' After Midnight," "Sweet Dreams" and others, she, along with the help of producer Owen Bradley, would define the Nashville Sound era--fusing pop and rock into country with luscious orchestral arrangements. Her legacy has been celebrated with such feature films as Coal Miner’s Daughter (1980), with Beverly D’Angelo, and 1985's Sweet Dreams, starring Jessica Lange. Now, Cline is the centerpiece of an upcoming PBS special, as part of their ongoing, award-winning "American Masters," which will feature never-before-seen archival interview footage given by her contemporaries and brand new interviews with a bevy of today's finest music makers.

The upcoming documentary airs March 4 in celebration of Women's History Month.

Reba McEntire, Rhiannon Giddens, LeAnn Rimes, Mickey Guyton, Kacey Musgraves, Wanda Jackson, Bill Anderson, Beverly D’Angelo and "Nashville" creator Callie Khouri all talk openly about Cline's influence on their careers. The documentary, with exclusive access to the Cline estate, will include sterling performances of such defining songs as “Three Cigarettes in an Ashtray,” “Come On In,” “I Fall to Pieces" and “You Made Me Love You."

“It’s been such a privilege to tell the story of Patsy Cline. For me, her story exceeds her musical accomplishments. She is in a rare class of women who simply set out to achieve their dreams and through those efforts left an indelible mark,” says Emmy-nominated director and producer Barbara J. Hall (Song by SongTitanic: Band of Courage) in a press statement.

“This film goes beyond the jukebox classics to show how Patsy Cline was really a gutsy pioneer,” Michael Kantor, American Masters series executive producer, adds.

"American Masters" was launched in 1986 and has earned an impressive 28 Emmy Awards, 12 Peabodys, an Oscar, three Grammys and two Producer Guild Awards, among countless other accolades. The upcoming 31st season also features new documentaries about Dr. Maya Angelou (February 21), Chef James Beard (May 19) and Chef Jacques Pépin (May 26).
