Seven Ark is a South-African musician from Cape Town, his real name is Justin de Nobrega and Seven Ark is only one of his aliases : he is in fact more known as "DJ Hi-Tek", as he followed his friends Watkin Tudor Jones and Anri Du Toit in their evolution from MaxNormal.TV to Die Antwoord.
Fun fact : his track "Sixteen" is also the name of Ninja's and Yolandi's daughter, but it isn't known if this track is named after her or if Justin did in fact influence his friends for the name of their daughter.
