Octavio and Gustavo Pandolfo also known as OSGEMEOS. Twin brothers born 1974 in Sao Paulo, Brazil. Their adventure with hip hop culture started with breakdance. In 1987, they discovered graffiti and gradually became the main influence on the local scene, helping to define Brazil's style. In their works, they combine elements of Brazilian cultural heritage with the convention of early New York street-art. Their work often features yellow-skinned characters – taken from the yellow tinge both of the twins have in their dreams. Subjects range from family portraits to commentary on São Paulo's social and political circumstances.
The twin brothers' mural located at 5 Roosvelta Street in Łódź was created in 2012 in collaboration with Aryz during the second edition of the Urban Forms Gallery.
