A group of 15 sculptures will become the latest to adorn downtown streets for two years beginning in June, organizers of the Napa ARTwalk exhibit announced.

At Tuesday’s City Council meeting, city and exhibit planners unveiled the pieces that will be displayed for the program’s fourth edition, which runs through May 2017. The exhibit will feature the work of artists from six western states, including the Napa artist John Bonick, who will contribute “Vine Vessels,” a cylindrical creation from steel, wire and grapevine cane.

Unlike the first three outdoor exhibitions, the latest ARTwalk will have no central theme, a step taken to open the display to a wider variety of sculptors, Jennifer LaLiberte, the city’s economic development manager said.

A jury of three art professionals winnowed the list of 165 applicants to 15, although the availability of one work was not yet confirmed as of Wednesday, she said.

Six of the featured works are from creators based in the Bay Area, including Oakland artist Lynne Streeter’s “One World, 2004,” a bronze and marble likeness of a tortoise on a stone slab; “Firebird,” a red fiberglass abstract by Oleg Lobykin of East Palo Alto resembling interlocking molecules; and “Your Cube, Sir,” a robotic likeness in steel by Jeff Owen of San Jose.

ARTwalk also will play host to a work transplanted from last year’s Burning Man festival in Nevada – “Getting Your Bearings,” a treelike installation created by David Boyer of Reno with a canopy of three wind-sock wheels that spin with the breezes.

Launched in July 2010 by the city and Arts Council Napa Valley, ARTwalk has served as a showpiece for a rotating group of sculptures placed along First and Main streets as well as Napa’s riverfront promenade.

Artists lend their works for two years, and their sculptures become guide points on a walking tour intended to increase foot traffic and interest in the city center.
