Thirteen-year-old twins Lamb and Lynx Gaede have one album out, another on the way, a music video, and lots of fans.
They may remind you of another famous pair of singers, the Olsen Twins, and the girls say they like that. But unlike the Olsens, who built a media empire on their fun-loving, squeaky-clean image, Lamb and Lynx are cultivating a much darker personna. They are white nationalists and use their talents to preach a message of hate.
Known as "Prussian Blue" -- a nod to their German heritage and bright blue eyes -- the girls from Bakersfield, Calif., have been performing songs about white nationalism before all-white crowds since they were nine.
"We're proud of being white, we want to keep being white," said Lynx. "We want our people to stay white ... we don't want to just be, you know, a big muddle. We just want to preserve our race."
Lynx and Lamb have been nurtured on racist beliefs since birth by their mother April. "They need to have the background to understand why certain things are happening," said April, a stay-at-home mom who no longer lives with the twins' father. "I'm going to give them, give them my opinion just like any, any parent would."
April home-schools the girls, teaching them her own unique perspective on everything from current to historical events. In addition, April's father surrounds the family with symbols of his beliefs -- specifically the Nazi swastika. It appears on his belt buckle, on the side of his pick-up truck and he's even registered it as his cattle brand with the Bureau of Livestock Identification.
"Because it's provocative," explains April of the cattle brand, "to him he thinks it's important as a symbol of freedom of speech that he can use it as his cattle brand."
Songs like "Sacrifice" -- a tribute to Nazi Rudolf Hess, Hitler's deputy Fuhrer -- clearly show the effect of the girls' upbringing. The lyrics praise Hess as a "man of peace who wouldn't give up."
"It really breaks my heart to see those two girls spewing out that kind of garbage," said Ted Shaw, civil rights advocate and president of the NAACP's Legal Defense Fund -- though Shaw points out that the girls aren't espousing their own opinions but ones they're being taught.
On that point, April Gaede and Ted Shaw apparently agree.
"Well, all children pretty much espouse their parents' attitudes," she said. "We're white nationalists and of course that's a part of our life and I'm going to share that part of my life with my children."
Since they began singing, the girls have become such a force in the white nationalist movement, that David Duke -- the former presidential candidate, one-time Ku-Klux-Klan grand wizard and outspoken white supremacist -- uses the twins to draw a crowd.
Prussian Blue supporter Erich Gliebe, operator of one of the nation's most notorious hate music labels, Resistance Records, hopes younger performers like Lynx and Lamb will help expand the base of the White Nationalist cause.
"Eleven and 12 years old," he said, "I think that's the perfect age to start grooming kids and instill in them a strong racial identity."
Gliebe, who targets young, mainstream white rockers at music festivals like this past summer's "Ozzfest," says he uses music to get his message out.
But with names like Blue-Eyed Devils and Angry Aryans, these tunes are far more extreme than the ones sung by Lamb and Lynx.
