“She brought a dignity to a woman’s feelings,” actress and singer Beverly D’Angelo says of legendary country star Patsy Cline in our exclusive clip of PBS’ “Patsy Cline: American Masters.” The “National Lampoon’s Vacation” and “Hair” star continues, “I think that the way that she sang with such feeling — and with such dignity — allowed any woman to feel, ‘You know, I am important. My feelings do count.’”

Widely considered one of the greatest and most influential singers of all time, Cline died in 1963 at the age of 30 following a plane crash. She’s sold millions of records, and in 1973, a decade after her death, she made history as the first female solo artist inducted into the Country Music Hall of Fame. Cline “defined modern country music by using her singular talent and heart-wrenching emotional depth to break down barriers of gender, class, and genre,” as per the film’s official synopsis. “Narrated by Rosanne Cash, ‘Patsy Cline: American Masters’ examines the roots of Cline’s impact to illuminate how she arrived at a pivotal moment in the evolution of American culture and synthesized country, pop, and rock in a new way.”

In addition to rare performances of songs such as “Walkin’ After Midnight,” “Come On In,” and “I Fall to Pieces,” “Patsy Cline: American Masters” features interviews with singers including LeAnn Rimes, Kacey Musgraves, and Wanda Jackson. But the interviewee at the center of this exclusive clip is The Queen of Country Reba McEntire. “‘Sweet Dreams’ was a song that I recorded because I’m such a huge fan of Patsy Cline and I would end the show with that, a cappella,” McEntire says.

The film is streaming now on PBS Passport, a members-only streaming service available in most areas and PBS OTT apps. Broadcasts continue all this month on PBS. Find more information on the film’s official website.
