Willys de Castro's artistic legacy stands as a testament to the foundational aesthetic principles that underpinned the Concreto group, a movement he played an instrumental role in co-founding. His oeuvre echoes with a profound engagement in matters of form and structure, delving into the intricate nuances of composition, rhythm, equilibrium, tension, and the delicate equilibrium within instability.

Within the realm of Linhas Tortas, his copper and brass creations resonate with a captivating evolution of his celebrated Pluriobjetos series. Merging wood, metal, brass, and copper, these pieces perpetuate the captivating choreography of part displacement. This dance transforms the conventional into the extraordinary, orchestrating an artful interplay between poised affirmation and an elegant celebration of disarray.

De Castro's work becomes a tactile symphony that bridges the essence of the abstract with the tangible allure of craftsmanship. His persistent engagement with these aesthetic precepts establishes him as a master of equilibrium amidst dynamic tension, a sculptor of both the visible and the unseen. The resulting artworks, forged from copper and brass, weave a narrative of contrast and cohesion—a testament to his ability to reshape materials into harmonious disarray, embracing chaos while inviting the observer into a realm of contemplative balance.
