Mauro 'Muretz' is a Brazilian artist mostly known for his street art work. He began working with arts at the age of 15, 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, Muretz enroled into college to study social communication but got frustrated shortly afterwards and abandoned the course. Muretz left Brazil and travelled to London in 2003 where he continued illustrating for a living. He also enrolled into a Masters Degree course at Central Saint Martins University.

After graduating, the artist returned to Sao Paulo and started painting on the streets. His works have been featured on street art publications, tv shows, magazines and newspaper articles around the world.
