East Nashville’s Octane! Gallery regularly brings what they describe as lowbrow art to the walls of Kustom Thrills, the tattoo studio where the gallery is housed. Their 2013 art show series offers a variety of exhibits with intriguing titles like “People I Know in Nashville When I’m Drunk” and “Rock Out With Your Clock Out,” and this weekend they’re featuring one of their own, tattoo artist Ryan McDonald. If you’re a fan of McDonald’s tattoo portfolio, you’ll likely be a fan of the paintings in his Occultic Illuminations show — think Egyptology and Illuminati-inspired graphics with the salty edge of a tattooed sailor. Admission is free, and all ages are welcome.
