After quite a history, Rosalux celebrates its staying power — and the multitudes of artists it has nurtured for the past 15 years — with a show that introduces emerging art makers while also honoring those established artists in our midst who continue to awe and inspire. That includes Shawn McNulty, creator of heavily slathered abstractions that beckon you to sink into their depths; Laura Stack, who merges scientific investigation and color innovation in her amorphous pieces; and Rebecca Krinke, maker of the fairy-tale feather bed series. Kim Tschida Petter’s letterpress ink and watercolor prints are swoon-worthy. Meanwhile, whimsical works by Jennifer Davis and Amy Rice, plus Dan Buettner’s wickedly humorous pieces, engage your brain — and your smile. And this is all just the tip of the iceberg.
