Aqua Arte
Justin "Scrappers" Morrison has organized a show to benefit the Willamette Riverkeeper, and it's sort of a who's who of local, middlebrow, illustration-based artists, like Bwana Spoons, Martin Ontiveros, Brett Superstar, and Amy Lynn Morrison. Reading Frenzy, 921 SW Oak, 274-1449, through July 29

New Photography 2006
Newspace's annual juried exhibition generally draws a nice crop of emerging photographers; this year Christopher Rauschenberg and Jennifer Stoots took the helm as jurors, so this one's a pretty sure bet. Newspace, 1632 SE 10th, 963-1935, through Aug 27

Joe Macca
At a solo show at PDX several years ago, Macca exhibited two bodies of work with nearly bipolar disparities. The main gallery found a suite of ethereal, gauzy abstractions that looked like gazing into a tropical sunset. The smaller show was of drawings he had sketched on toilet paper rolls, each more sardonic and funny than the previous. It was like the "Funny Joe/Serious Joe" show. Looks like this time we get Serious Joe, with new paintings based on his meditation practice. PDX, 925 NW Flanders, 222-0063, through July 29

Richard Rezac
In one sense, Rezac's solo exhibition is an anti-climactic follow-up to its predecessors (Sophie Calle's Exquisite Pain and Roxy Paine's PMU), but Rezac's understated forms mark a welcome departure from Calle and Paine's concept-driven work. The show also marks something of a return to Portland for the Chicago-based Rezac, who graduated from Pacific Northwest College of Art in 1974. Rezac's sculptures are deceptively simple in their minimalism. They are composed of the most basic geometric forms and rendered in traditional sculptural materials, such as wood, steel, and bronze. Many will find that Rezac's sculptures speak too quietly or fail to reveal themselves immediately—and, with a number of the show's pieces, this is certainly the case. Portland Art Museum, 1219 SW Park, 226-2811, through Sept 10, $6-10
