Paul Modjadji is a South African diamond - rare, and in demand.The two-time world dance champion leaves for the US tomorrow to perform in Washington DC at a South African gathering, the Freedom Day picnic celebrations.The dancer, choreographer and entrepreneur is known for his role on local e.tv soapie Backstage and as the choreographer behind South Africa's first dance film, Hear Me Move.Speaking to The Times, Modjadji said he would perform a contemporary solo piece, Viva the Legend, a tribute to Nelson Mandela.He added: "It's a huge honour to be able to promote and celebrate what it means to be South African," he said.This is not Modjadji's first trip to the US. Last year President Barack Obama honoured him with a Mandela Washington Young African Leaders Award.Modjadji will be speaking at schools about South Africa's democracy."We need to understand as artists in South Africa that we must share our story with the world, to change the perception that we are in a dark corner."Our story is about how we as young people are enjoying our freedom," he said.Modjadji will also attend screenings to promote Hear Me Move , ahead of its US release in October. He said the film was a glimpse into the local dance scene."South African dance is at its best," he said. "More dancers are professionalising the art and are able to make a living from it. The biggest challenge we face is access to the art. I realised I had to think outside of my community."The story of South Africa is not just for us. It's important to export our talent."If we don't play in the global market, we'll fade away."Modjadji will be a judge at the International World Dance Championship in Europe next month and in July he begins his African tour.He said the tour was his way of "expanding" his roots as he will be providing dance clinics in South Africa, Kenya, Congo, Zimbabwe, Lesotho, Botswana, Namibia, Uganda and South Sudan...
