This lady walks around the streets of Recife, in Brazil, selling stools. She collects wood from a landfill, cuts it at a friend's workshop and paint it, transforming the dirty wood into small stools which she sells for 5 reais (2,50 euros). The difference is that she sings to sell them. And she has one of the most powerful voices I've ever heard.
Please share this video. A record company should hear this and help this woman.
