Like some kind of superhero venue, Theory + Practice lives a double life. By day, it masquerades as an art gallery, but once night falls and a sound system and a few lights are added, it transforms into the sweetest underground dance venue in town. It has a central location, nice acoustics, a fine floor for dancing — and it's just the right size to feel both intimate and spacious. Of course, the real kicker is that the promoters who favor it have done a fine job of bringing in top talent from the real underground, making for some great experiences at this dark knight of dance venues.
