Signmark, alias Marko Vuoriheimo, from Finland is a rapper - and he's deaf. His message to deaf people is that they need to stand up for their rights!
He's never seen his deafness as a hindrance in his career and says that he and his band are a well-practiced team. If the rest of the world knew sign language, he says, he wouldn’t need an interpreter. So is he disabled or just a linguistic minority?
