Ertza began in 2004 under the direction of the dancer and choreographer Asier Zabaleta (Ezkio, Gipuzkoa 1972). It was established to create a new realm for free expression, blending various artistic disciplines with contemporary dance.
Ertza's works pose questions regarding human and societal contradictions. With a playful and aesthetically pleasing approach, they invite spectators to take an active position concerning what they see and to reflect it on modern, everyday issues.
Since its creation, Ertza has presented its work in countries such as China, Philippines, Brazil, Peru, Costa Rica, El Salvador, Mexico, Israel, Russia, Lithuania, Luxembourg, Switzerland, Germany, France, Italy, Greece, Poland, Portugal, Korea, Hungary and Mozambique.
