Matthew Stromberg uses a wide variety of powerful and volatile substances, including rocket fuel, explosives, gunpowder, propellants and bullets, aka energetic materials, in order to create art rather than destroy. The Savannah College of Art and Design professor utilizes these forceful methods to apply his mark to wood, metal and paper. The results are quite visceral and evocative of the violent patterns of nature-- images seared and impressed in high-energy events. They kick ass, too.
Uncertain Times has videos of Stromberg at work with rocket fuel, homemade explosive, and a submachine gun. Link -Thanks, John!
