Such as life itself, Castill’s works are complex in volumes, colours and textures. Departing from one material, steel, the artist is able to represent his emotional univers, rich in contrasts, contradictions and diversity of feelings. His sculptures, denominated “sounder”, represent a beat in the dark. Materialized as a sound wave, the rhythm of life generates peaks and valleys disturbing the apparent serenity of the universe. Castill’s sidereal art exposes the materiality of steel in diverse ways, the raw and rough aspect of the untreated plates contrasts with the colourfully painted and polished volumetric elements.
This series has a big psychological charge, it allows us to discover the author's personality. The pieces invite the beholders to analyse the artist’s mind, to ask themselves what the Sounders are supposed to represent and how the artist has been able to bend such a strong material as steel. This material serves the artist to reflect his entire personal cosmos, as paper and ink might serve us to write down a thought. Due to the strong link between Castill’s psyche and his works his tshow appears as an undiagnosed pathology; therefore we invite the visitors to analyse it and discuss with the author in order to try to diagnose it. Undiagnosed exposes the artist’s character and the strong presence of his work, the pieces disturb the calm of the space they invest. The contrast between the ecstatic and the dynamic part makes the viewer be alert, showing the possibilities and the limits of steel.
The Sounders series plays with the architecture of the gallery. Both the result of industrialisation, the pieces and the space establish a dialogue emphasising the beauty of heavy and revolutionary materials. The works invest the architecture becoming more than a sculpture, they can be appreciated as an element composing and dividing the space. Hanging on the wall or leaning on the ground, the Sounders have the virtue to shape a new three-dimensionality.
