‘The “Tunnel Boring Machines” are hybrids, mixed beings, that come out of a very rough mud shell, from which animal fragments emerge, fins, beaks, prehistoric beings that make up the terra incognita on which we tread every day. They are hybrid animals. Their shapes resemble propellers, the teeth of mechanical diggers, the same machines we use to excavate this prehistoric earth. There is something very sexual in them. They look like things that penetrate each other, and respond to the logic of a land that is saturated with sex and fertility in its pure state. There is also something digital, almost as if their existence were slightly virtual, to do with the treatment of shapes and colours. And yes, they all see them as pieces that straddle the path between a simulated space and the geological space I’m referring to.’ When Teresa Solar Abboud presented her ‘Tunnel Boring Machine’ at the Venice Biennale in 2022, this is how she described her gigantic sculptures. Hybrid beings that appeal to the senses in a very direct way. Located in the Tower of the main MACBA building, they generate an intensely physical sensation.
