Mauro 'Muretz' is a Brazilian artist mostly known for his street art work. With family roots and born in the East Area of São Paulo (ZL), he was raised in a small town in country side. He began working in arts at the age of 16 as a freelancer after getting expelled from school and had to start earning a living doing exactly what got him kicked out: drawing.

Around 18 and pressured by friends and family, young Muretz enrolled into college studies but got frustrated shortly afterwards and abandoned the course in disgust. Frustrated, the artist later left his country to go to London in 2003, where he could more easily make a living working with passion. He also enrolled into a Masters Degree course at Central Saint Martins University, which he also abandoned for financial problems.

After this time, Muretz returned to his birth town and started painting on the streets. His works have been featured on graffiti and street art publications, even tv shows, magazines, newspaper and articles around the world.

The artist currently lives and work in the West Area of São Paulo city.
