The closest thing to a one-stop shop of underground downtown culture is this bare-bones space carved out of an old brick building on Roosevelt. It's strictly an after-dark joint. The lights typically don't go on until 7 p.m. But once they do, the offerings are just as likely to include exhibitions by painters, sculptors and performance artists as they are performances by dancers, poets, jazz players and punk rockers. The featured artists are largely up-and-comers -- the bands are some of the primo ones on the indie music circuit. And the swarm of culture-driven people who fill the dark streets around the arthouse helps to strengthen the human beat of the old heart of the city.
