This weekend, three buildings housing nearly 500 artist studios will open their doors, inviting people to see exactly what Northeast creatives have been up to. Hot off the announcement that the building has been purchased by Artspace, Northrup King Studios (1500 Jackson St. NE) hosts Art Attack, showcasing a mind-boggling 350 artists. Check out ceramic work ranging from practical mugs to showy large-scale sculptures, giftable jewelry, and dog portraits in a variety of styles. Over at the California Building (2205 California St. NE) is California Dreaming, featuring more than 50 open work areas, studios, and shops. Check out Aldo Moroni’s collection reflecting on his 45 years creating work in Minneapolis. Drink some java at Mojo Coffee, and score some affordable art at Studio 201’s show and sale. You may want to end your day (or start your evening!) at Open Casket, Casket Arts Community’s (681 17th Ave. NE) art party highlighting 80-plus artists. On the fourth floor you’ll discover free live music, while the basement will offer special cocktails and burlesque performances. On the street, food trucks will be selling smoked meats and Egyptian treats.
