This week you’re in for a weird ride. From Aaron Pexa’s installation inspired by faeries from Welsh mythology (opening Wednesday at UrbanGlass) to a show of fake John Waters memorabilia Thursday night at La MaMa, there’s a lot of idiosyncratic happenings to partake in. Add to that itinerary a Friday night group show of emotion-altering colors (like the opposite of a mood ring!) at Small Editions and Eva Papamargariti’s speculative mutant frogs at TRANSFER on Saturday.

Aaron Pexa: The Spoils of Annwn

Inspired by a Middle Welsh epic poem, “Preiddeu Annwn”, this immersive installation references King Arthur’s mythical voyage to the Glass Fortress, home of the faerie folk. Aaron Pexa is bringing this tale to life through surrealist glass sets, neon, video, light sculptures, and illustration.

All of this is supposed to evoke a feeling of “werifesteria,” which means to wander longingly through the forest in search of mystery.
