Tellas was born in 1985 in Cagliari, Sardinia. His artistic journey begins in the harsh lands where he grew up. His work is a personal and intimate vision of the natural elements defining the landscape around him. Each piece is the result of a meditative process combining spatial qualities, shapes and species of the surrounding environment. He expresses his style through various means. His use of drawing, painting, printing techniques, installations and audio-video production confirms his aim to create and experiment with different art forms.
He participated in many international events. Among the most remarkable there are the La Tour Paris Project, 2013, considered one of the most innovative contemporary art projects worldwide, and Artmossphere, the first Street Art Biennale held in Moscow in 2014, featuring 70 artists from all over the world.
