Alptraum nr1 by Christian Rosa is a dynamic and visceral work that layers oil paint, charcoal, pencil, resin, and rabbit skin glue onto canvas, creating a richly textured surface that feels both raw and deliberate. Rosa's signature gestural marks surge across the composition, blending frenetic energy with moments of haunting stillness. The interplay of materials lends the work a dreamlike yet unsettling quality, evoking the disorientation suggested by its title, which translates from German as "nightmare."
