His work questions cultural and social reality from a late-Romantic perspective with a critical edge. Through a continuous exploration of the social imaginary, Sala pinpoints its sore spots, demonstrating the power of art as a space for experimentation and for imagining new worlds. A key Spanish reference for art as a vehicle of political resistance, his practice develops a kind of poetics that reflects on state power and the systems of control it exerts. His distinctive aesthetic language is as necessary as it is forceful, addressing sensitive and pressing issues such as migration, contemporary dislocation, the environmental crisis and the paradoxes of capitalism.

Sala operates within the global context of contemporary art, exhibiting and participating in biennials in Caracas, Tel Aviv, Istanbul and other cities. His work has been shown nationally and internationally at institutions such as Abrons Arts Center in New York, the Museum of Fine Arts of Asturias, MAAC in Guayaquil, the National Centre for Contemporary Art (NCCA) in Moscow and Matadero Madrid, among others. He has received several grants, including those from Cajastur, Hangar, BilbaoArte and the Generaciones Prize from CajaMadrid.

He has also been a grant-holder at the Royal Academy of Spain in Rome and at Le Lait Art Centre in Albi, France (2012).
