Duck into a dark mini-alleyway off Belltown’s Second Avenue (we’re not giving you the cross streets), and you’ll stumble onto some impressive graffiti. Pieces of the urban art puzzle are hidden all over town, especially in its farthest corners. For a broad view of styles, check out the unveiling of a 160-foot spray-paint and acrylic mural today in Georgetown, made collaboratively by 14 reportedly notorious graffiti artists. You can see this permanent work of art anytime, but there’s music today and munchies.
