During Georgetown’s monthly Art Attack walk, the newish gallery LxWxH brings you a crew of four local lady metalsmiths, all making jewelry that could either protect or attack you. Dorothy Cheng has an interest in medieval mortification of the flesh—hair shirts and whatnot. Jana Brevick’s pieces often look like they are guilty of transmitting secret data across surveillance systems. Kimber Leblicq dips steel in beeswax and juxtaposes it with rolled-up paper that looks burned. Tara Brannigan’s ring has a duiker horn instead of a precious gem. Something’s gonna get stabbed.
