"'Caldera' is free form, three separate pieces making up a narrative. As with many of the recent pieces it features an homage to the artists who painted in the caves of Lascaux, 30,000 years ago.
A caldera is a volcanic crater that has a diameter many times that of the vent and is formed by collapse of the central part of a volcano or by explosions of extraordinary violence. Spanish, literally, for cauldron."
