There will be a pop-up exhibition of paintings by Waldoboro artist Krisanne Baker, as well Piano Roll Project by several other artists, during the year’s final First Friday Dec. 4 from 5 to 10 p.m. at the Portland Garage, 173 Neal St.

Water-centric eco artist Baker will exhibit encaustic oil paintings that keenly examine the rhythms and sensations of ocean water above and below the waterline. Baker’s abstract, yet representational, installation of five piano rolls with phosphorescent panels alludes to viewing a kelp forest and jellyfish from the sea floor.

Her “Warm Sea Weed Salad with Moon Jelly Compote” installation was conceptualized to raise further awareness to the problem of global warming and its worldwide effects on the ocean and the planetary food chain.

A selection of artists from “The Piano Roll Project: Shared Sensibilities,” an exhibit of 30 artists working in Maine (and several outside of Maine) invited by co-organizers Kristin Malin and Gail Skudera, will exhibit their piano rolls. Artists responded by altering a vintage player piano roll, some as long as 40 feet, with their own artistic expressions, transforming an audio medium into a visual one.

Artists were encouraged to paint, draw, cut, tear, collage, write, sew or weave with the continuous roll of perforated paper. Highly valued was how each artist would interact with the inherent beauty and pre-digital language of the roll. Participating artists include Baker, Northport’s Stew Henderson, Paula Heisen, Jung Hur, Joël LeVasseur, Heather Lyon, Kristin Malin, James Provenzano, Barbara Sullivan and Kathleen Sweeney.

The First Friday program also will include musical performances by Jim Goss, members of No Money Down, Dean Ostergaard and Todd Fiske. The public is invited. For more information, contact Baker at baker93@yahoo.com or 380-7449; or Malin at kristinmalin117@gmail.com or 751-4999.
