Decades before BTS, Blackpink, and ‘KPop Demon Hunters,’ the Korean trio took Vegas and Ed Sullivan by storm. Here, surviving member Sue Kim tells their unbelievable story—from abject poverty to sharing a marquee with Elvis.
That is, until the Kim Sisters: three stunning Korean women who could harmonize like the Andrews Sisters, work a stage like seasoned Vegas pros, and switch from accordion to drums to guitar without missing a beat, all while wearing sleek mod dresses that caught the stage lights just right.
Their cover of “Charlie Brown,” a Coasters’ doo-wop hit, was released as a single by Monument Records in 1964, cementing them as the first major Korean crossover success. Sook-ja “Sue,” Ai-ja “Aija,” and Min-ja “Mia” Kim paved the way for future K-pop invasions with an astonishing 22 appearances on The Ed Sullivan Show, glossy spreads in Life and Newsweek, a Las Vegas residency that lasted 15 years, and prime-time television performances on juggernaut variety programs like The Dean Martin Show. Their story—forged amid war, murder, and deprivation—has long lived in the margins of pop history. Their legacy has only recently been rediscovered, in part thanks to Netflix’s most-watched film ever: the animated blockbuster KPop Demon Hunters. “When I first learned about the Kim Sisters, I remember thinking, How in the world, in the 1950s, did a group of Korean women make it onto The Ed Sullivan Show?’” says Maggie Kang, the film’s codirector. “It seemed unimaginable—but at the same time it made so much sense.” Kang may also be talking about the inevitability of her own film’s rise. Now nominated for two Academy Awards, including best original song for “Golden,” the first K-pop song to win a Grammy, KPop Demon Hunters follows HUNTR/X, a fictional trio of Korean singers who battle underworld creatures by uniting their voices and forging direct connections with their fans. The Kim Sisters—actually two sisters and a cousin, who performed under Americanized names—were similarly shaped on a battlefield that receded only through song. Their discipline, versatility, and sheer magnetism propelled them into midcentury rooms that few Asian or Asian American performers had ever entered. Sue Kim tells the story best. Now in her 80s and still living in Las Vegas, the group’s de facto leader retains the unmistakable bearing of a showbiz professional. Presence, timing, and the ability to form an immediate emotional connection—even across a single interview—remain second nature to her. Asked about her exact age, she shrugs and answers, “Who cares?” When Kim was in Korea in 2022 to celebrate her family’s legacy, she says, “The papers thought the Kim Sisters were all dead. Now, suddenly, because of Demon Hunters, they’re saying you guys are the original HUNTR/X.” She pauses, then laughs. “So, my husband and I watched the film. Now I understand.” The Kim clan conquered real demons long ago. Kim vividly recalls how her privileged childhood—“We had a huge house with 13 different rooms, like a palace”—ended just days after North Korea invaded South Korea in 1950. North Korean forces imprisoned her father, the celebrated conductor, composer, and bandleader Kim Hae-song. The reason why was never fully clear. Sue Kim’s memory is. “I saw seven soldiers with machine guns, marching in step, coming toward our house,” Kim says. “They opened the sliding door, put a gun on my father, and handcuffed him.” Later, the militia came for Kim’s mother, Lee Nan-young, a beloved singer whose recording of “Tears of Mokpo” is now widely considered an unofficial Korean national anthem. As Kim explains it, the soldiers imprisoned her in a cave with 16 others and were supposed to “assassinate them.” Her mother begged to be released, citing the seven children she had left at home. Compassion, improbably, won out. More than one million civilians are estimated to have died during the Korean War. Yet all seven Kim children, their mother, and their aunts survived. “That was the most incredible thing,” Kim says, pausing for a long moment. Her father was not so lucky. He was dragged toward North Korea; some prisoners died along the forced march, Kim says, and a large group was eventually lined up on a bridge and shot. Later, she walked back to what remained of her neighborhood only to find “dead bodies all over the street.” Much of the Kim clan’s once-opulent house had burned down after being looted, Kim says. Poverty became a way of life overnight. Surviving relatives—more than 20 people in all—lived together in what remained of the home, a shed that had once stored backdrops for productions of Romeo and Juliet and Carmen. “We didn’t have any food. We didn’t have any rice,” Kim says. “Those are the most difficult times I remember—how hungry we were.” They survived thanks to Kim’s mother’s resourcefulness—and her idea to make money by entertaining American troops. The US troop presence in South Korea reached its peak in 1953 at 326,863, with large numbers remaining even after the armistice was reached that year. The Kim matriarch’s idea was a precursor to today’s K-pop training model: Form a group. Rehearse relentlessly. Entertain. But rather than performing Korean ballads, the group would lean on material that was becoming universal: American novelty songs. In 1951, Sue and Mia were about 11; Aija was around nine. Knowing that nostalgia would appeal to soldiers far from home, Kim’s mother bought a Rosemary Clooney album on the black market, and taught the songs phonetically to the girls. The three girls practiced on the train to their first gig at a GI club in Busan, singing with Kim’s surviving parent in what she still calls a “mama and baby show.” Although they’d memorized English lyrics, they had no idea how to converse in English. The response was immediate. “I can remember it just like yesterday. They were stamping their feet, and they would go, ‘More, more, more,’” Kim says. “Without the GIs, I don’t know what we would have been.” The sisters were paid in booze by the soldiers, then used the black market to trade alcohol for rice, Kim says. The Kim family kept performing in Korea until the late 1950s, with Kim gradually taking more of a lead role. By then their repertoire had expanded. “We were singing ‘Sincerely’ by the McGuire Sisters,” Kim says. “And also, rock and roll, like ‘Jailhouse Rock.’ You name it, we sang it all.” By the mid-1950s, Las Vegas was entering its Golden Age: a swirl of luxury hotels, smoky glamour, and legendary casinos like the Sands, the Riviera, and the Tropicana. What the city needed almost as much as martini glasses and poker chips were entertainers. The stars aligned when Vegas producer Tom Ball began assembling a show called the China Doll Revue for the Thunderbird hotel and went looking specifically for Asian acts. The Kims were focused on opportunities; here was one, even if its name was marred by 1950s racial shorthand. “We couldn’t think of those things at the time,” Kim says, returning to the practical reality of survival. “My mother sat me down and said, ‘Look, you’re going to go to America. This is your meal ticket.’” The subtext was clear: Don’t mess up. “My mom told me, ‘You can’t come back without success.’” Sue and Mia were around 19, and Aija about 18, when they left their mother and their country. They still couldn’t speak English well. “We were scared. Really, really scared,” Sue Kim says. “We didn’t even know where America was. And we’re coming here without our mother. It was a horrible, horrible experience. Because first, there’s America, then there’s Los Angeles—but then there’s Las Vegas.” “They took us to the Thunderbird Hotel. It was like a palace,” Kim says. “We opened. I had a lot of pressure. But I knew that if I worked hard, we could make it.” The revue—which Kim says included 18 Japanese dancers, two Chinese dancers, and a comedy act—ran 90 minutes. On opening night, parts of the scenery began collapsing mid-performance. Ball watched nervously, waiting for the girls to panic or stop. They didn’t even blink. Performing in traditional Korean hanbok and heavy rubber shoes, the Kim Sisters were an immediate hit. Their name soon moved to the top of the marquee. Tommy McDonnell, the host at the Stardust resort and casino, saw them perform and brought them over. That, Kim says, was “the beginning of our history.” At the Stardust, which billed itself as the world’s largest hotel when it opened in 1958, the Kim Sisters performed six half-hour shows a night in the lounge, with 20-minute breaks in between. “Our job was the people coming out of the showroom,” Kim says—to keep them in the hotel so they would keep gambling. But the toll of entertaining the masses was physical and unrelenting. Each night, the women dragged themselves to the dressing room, feet raw and bleeding, barely able to walk. “That’s how much we were hurting,” Kim says. “But we had no choice. We had to do it.” “We worked. That was our life. We eat, we sleep, we work. Sometimes without sleeping for 24 hours.” She pauses. “But we loved it. We loved being entertainers. We loved the stage.” One thing nearly defeated them: “We couldn’t eat Korean food,” Kim says. Soon, Aija fell ill.“We’ve got to have kimchi to have power,” Kim explains. “We grew up with this, and we can’t live without it. That’s our food. It’s like a potato here. You know what I mean?” She laughs. “But these potatoes are not as exciting. Not as exciting as kimchi.” Eventually, they began making pilgrimages to Los Angeles for salted, fermented vegetables. They also gradually moved away from their traditional dress. “It’s hard to dance in a hanbok,” Kim explains. By then, the Kim Sisters had their routine down, moving in sync. Mia was the cool one who never missed a cue. Aija was all spark and edge on upright bass. Kim projected easy warmth when she blew the tenor sax. It’s one of the 14 instruments she mastered, she says before correcting herself. “I forgot the bagpipe. So it’s 15.” That’s when they were called to perform for a TV program that regularly made history. The Ed Sullivan Show wasn’t a revue or a lounge but America’s living room. In the late 1950s, when most households owned a single television, about 40 million people tuned in each week. Sullivan regularly anointed stars and cultural icons with a single appearance, beaming performers—Elvis Presley, the Supremes, and the Beatles—straight into homes that might never otherwise encounter them. In September 1959, less than one year after their arrival in the United States, he did the same for the three young Koreans from a live broadcast featuring taped sections from the Stardust hotel. “Here they are,” Kim recalls Sullivan saying in his unmistakable deadpan. “The Kim Sisters. From Korea.” It’s hard to overstate what introducing Americans to an act from Korea meant in that moment. These were women who had once gone hungry in a country Americans knew mostly through “red scare” headlines and battlefield footage. Now they were standing in front of TV cameras singing in English they couldn’t yet read, broadcast live into millions of American homes. The trio performed the McGuire Sisters hit “Sincerely.” Their later appearances featured “Charlie Brown” , an astonishing medley from The Sound of Music, and the trio tearing through what may be one of the most electric renditions of “Fever” ever captured on television. Scroll through the comments beneath the official Ed Sullivan uploads, and the lineage of K-pop is spelled out in real time. “Beginnings of BTS and Blackpink,” one viewer writes. Another adds, in Korean, “선대 헌터분들이 계신다고 해서 찾아왔습니다.” Loosely translated: “I came because I heard there were hunters from the previous generation.” As their profile rose, the sisters stayed tightly bound by their mother’s rules. “Until you’re successful, no dating,” Kim remembers her saying. “Because when you’re dating, you break up the group.” She laughs, then adds, “She was right.” Mia and Aija both married drummers in 1967, one month apart. Kim also got married—to John Bonifazio, a legendary casino boss. “I saw her and that was it,” says Bonifazio during our interview, infatuated with Kim to this day. The sisters continued performing through 1973, spending 15 years on the Stardust stage. Then, says Kim, “Mia left to pursue her own life.” She and Aija kept singing together, at one point sharing a marquee with Elvis, until 1987, when Aija died of cancer. Mia lives in Hungary with her husband. “When Aija died, I couldn’t get onstage without her,” she says. “The first time, I really couldn’t.” She pauses. By then, Kim had brought her older sister—and later, her brothers—into the act. “They literally pushed me and said, ‘Sister, think of us like Aija, like Mia. Think of us as the Kim Sisters.’” Kim hoofed and sang and strummed and blew her way across stages worldwide until 1995, all while raising two children. It’s taken decades for Kim to slow down and absorb the scope of what she, Aija, and Mia accomplished. She spreads out piles of Kim Sisters clippings across a table, examining them like artifacts from another life. Friends and family now buy her memorabilia on eBay—playbills, magazines, advertisements she never knew she appeared in—filling in the picture after the fact. Kim’s mother, Lee Nan-young, died in 1965. In 2006, her remains were moved to a memorial in Mokpo, a long-overdue recognition of her place in Korean cultural history. Now her daughters’ legacy is circulating again, carried across Korea, the United States, and beyond by YouTube clips, Instagram tributes, nostalgia, and—unexpectedly—demon hunters. “I go through this and I say, you know, we were quite big,” Kim says, leafing through copies of Life and Newsweek that feature her smiling face. Before YouTube launched, she had never actually watched herself perform. Kim is genuinely puzzled by the clips: “How could three people breathe at the same time? I never told Aija and Mia, ‘You should move that way. You should do this.’ Never. We rehearsed, we went onstage, boom. We did it. Flawlessly.” That instinctive cohesion helped plant the seed for a more modern cultural sensation. “Even in the 1950s, the power of Korean music was uniting people and bridging the cultural gap between Korea and the US, just as it does today,” director Maggie Kang says. “The fact that the Kim Sisters, a group of Korean women, were the first to do that—how could we not be inspired by them?”
