GROTON -- Harvard-based printmaker Pam Lawson and her longtime friend and associate, Heather K. Lenz, have compiled an exhibit of prints and paintings that nearly vibrates off the walls of the Owen Smith Shuman Gallery.

The exhibit is on display currently through Saturday, Jan. 18. All are welcome to a reception with the artists on Thursday, Dec. 12, from 6:30-8 p.m.

"A Flock of Days," aptly titled from the passage of a poem by the late Carlisle-based poet Judith Goodenough, suits both artists in sublime fashion:

At the pasture pond

A flock of days

Rises and is gone

Pam Lawson's red-winged blackbirds are real in a way that only a partial abstraction of a living thing can achieve. It is as if they are arrested in a moment, suspended in air, heart fluttering, chest expanding, wing tips slightly raised. Pam's technique for painting with rollers allows her to play with color and composition in a spontaneous fashion. Working quickly on a plexiglass plate with oil-based inks, she captures the essence of bird, sky and grass.

In creating layers in oil paint on panels, Heather Lenz provides a method of diving into her work. Floating on the surface is an opaque layer of rolled on oil paint representing the surface of the water on which float lily pads and pond scum, a semi-permeable membrane through which can be seen the glittering colors of a riotous New England fall. The colors themselves are merely a reflection of what is happening above the surface, obscuring the darker, colder space beneath the water. Delving in, the viewer is invited to explore not just the painting, but the meaning of reality itself -- the question of what is real, and how much of what we see is merely an illusion, a floating world.

This exhibit is made possible by the Groton Public Library Endowment Trust. Works by P.C. Lawson are on display courtesy of the Powers Gallery in Acton.
