Art Spark is a monthly series where artists meet to discuss the usual (art, art, art) but with a more strategic bent- what's the Portland art scene doing, where's it headed, and where should it go? This month's meeting will focus on film, led by director Andy Blubaugh. He'll even shoot a short film at the rooftop space, starring you (if you show up). If that's not enticing enough, attending is also a way to backdoor free admission to the Top Down screening of Marx Brothers classic Duck Soup.
