The polar vortex and an accident with the city’s water main disrupted the opening reception in January for artist Jodi Reeb’s latest exhibition, “Re-imagined Landscapes,” at Concordia Gallery. This week, she’s giving it another try. The show features Reeb’s mixed-media work, created using photographs and encaustic paint (aka melted beeswax). The effect is luminous, with pieces that have an almost cinematic quality, and somehow also evoke the melancholy mood of a rainy day. Reeb focuses on the horizon line for this collection, exploring its metaphorical possibilities as she uses her memory to recreate landscapes. Meanwhile, sculptor Priya Thoresen’s latest exhibition, “Material Presence,” uses ceramic materials in unconventional ways to create three-dimensional objects.
