Courtney Kenny Porto pulls together a good group show, and this time she's coordinating more than 70 local artists for a weekend pop-up that promises bright colors, bold strokes and a wide range of price points. "Vivid" runs the evenings of Friday and Saturday, Oct. 10 and 11 and the afternoon of Sunday, Oct. 12. Clover24 is a new art space at 24th and Martha streets in the remodeled Kitty Clover potato chip factory. I have two small abstracts in the show, including the image in the top left corner of the promotional graphic.
