Traffic Zone Artists Open Studios

More than 30 artists will welcome visitors to Traffic Zone in an annual ritual that grows a bit more ambitious every season. Twenty-one artists have studios at the TZ, conveniently located where Interstate 394 disgorges onto Washington Avenue N. in the Warehouse District. This year several of them have invited friends to share their spaces for the evening, so the building will be hopping with black-and-white photos, colorful abstract paintings, minimalist sculpture, moody landscapes, Chinese-modern landscapes, whimsical prints, moire-patterned designs and more. -Mary Abbe

'UNDR MPLS'

Minneapolis is a haven for urban explorers, who have been delving into abandoned mills, warehouses and early tunnel systems for decades. Out of this movement has come a unique arts scene that has captured the excitement of the underground via photography, "light painting" (a photographic technique in which long exposures are made while moving a handheld light source) and other subterranean projects. These works come to light in a one-night-only exhibition at the up-and-coming Future Presence Gallery. The various projects will be showcased on both levels of the gallery through a range of installations as well as photographic and video documentation made in collaboration with dozens of local explorers and artists. -Jahna Peloquin
