There is nothing decorative about a Jason Shiver sculpture. Metal pulled, shaped, and welded into forms that feel like they have been here longer than the materials allow. War Horse carries the weight its title promises. Something ancient in the posture, something unresolved. Self-taught, raised in St. Petersburg in the shadow of the Dali Museum and the Ringling, he eventually took his practice to Shanghai and Tokyo before coming back to Tampa. His work explores the relationship between humans and the natural world. He aims to provoke a strong reaction. He succeeds.
