They earned a dubious fame in 2003 with their white power band Prussian Blue, but twins Lamb and Lynx Gaede have apparently turned their backs on their neo-Nazi roots and embraced peace, love and liberalism.
The blonde, blue-eyed girls named their band after a by-product of the poisonous substance used to gas Jews during the Holocaust, a moniker suggested by White Nationalist leader William Pierce.
They penned race hate pop tunes entitled Hitler Is Our Hero and Aryan Man Awake, were filmed performing Nazi salutes on stage, and received hate mail after suggesting the execution of Jews during World War II was “exaggerated”.
Their childhood saw them home-schooled in Bakersfield, California, by their mother April Gaede, herself a member of racist fringe groups the National Alliance and the National Vanguard. Her own father, Bill Gaede, wore a swastika belt buckle and even branded his cattle with the sign, The Mirror revealed.
But now aged 20 and having experienced a string of health problems including cancer, the girls say they’re embracing a hippy lifestyle – with the help of marijuana.
Both girls have Montana-issued medical marijuana cards and describe themselves as “healers”.
In 2011, Lynx exclusively told The Daily: “I have to say, marijuana saved my life. I’d probably be dead if I didn’t have it.”
Lamb added: “We just wanna exert the most love and positivity we can.”
In the same interview Lamb describes herself as "pretty liberal", while Lynx chipped in with: “Personally, I love diversity! I’m stoked that we have so many different cultures."
Their comments are in stark contrast to an TV interview they gave ABC News in 2005, where Lamb branded Hitler "a great man" with "a lot of good ideas".
Lynx added: "Lots of things were exaggerated about the Second World War.
"We don’t believe that six million Jews were executed. I mean, there were not even that many Jews alive then."
In 2007 the girls gained fame in the UK after they were filmed performing "the dance around the swastika" in a documentary about Nazis as a bemused Louis Theroux looked on.
But while the pair have seemingly experienced a significant turnaround, they appear to stop short of completely renouncing their roots.
Asked last year whether the Holocaust happened, Lynx replied: "I think certain things happened. I think a lot of the stories got misconstrued.
"I mean, yeah, Hitler wasn't the best, but Stalin wasn't, Churchill wasn't. I disagree with everybody at that time."
Lamb added: "I just think everyone needs to frickin' get over it. That's what I think."
