Each second Friday of the month, the art spaces centered around the renovated factories and warehouses at 18th and Halsted in East Pilsen open their doors and put out the free food and booze to wrangle in the public. Tonight from 6 PM to midnight the 2nd Floor Gallery at 903 W. 19th hosts Ache. The evening has a distinctive goth flavor, featuring DJ Peter Propaganda of BondageNightChicago.com and artist Eric Freeman, the Cleveland satanist also known as DarkLord10000000 (he's received plaudits like "angry, crude and offensive"; that's his work to the left). In total, 21 artists and fashion designers will show their work. Rapper V8 and rockers RobotPanicMusic will each play a set. The Glitterguts mobile photo booth provides the necessary self-documentation, for free of course.
