This weekend, artists will open the doors to their lofts, galleries, and studios to showcase their work at the semi-annual Saint Paul Art Crawl. Over 400 artists will be participating in 30-plus buildings. While things are concentrated in Lowertown, happenings can also be found along Raymond Avenue, University Avenue, West Seventh Street, and downtown. The Schmidt Artists Lofts will have live music and demonstrations, plus knit goods, pottery, paintings, and more. The Lowertown Lofts Artists Collective will host fire dancers and flash-mob violin performances. Carleton Artist Lofts will offer free massages and artwork from the late Chris Cornell; meanwhile Interact Center will have ice cream treats. Download a free ride pass from MetroTransit and head into the neighborhoods to explore. For more info and locations, visit www.saintpaulartcrawl.org.
