This double bill from Theater o’ th’ Absurd and II Roman Senators Productions wouldn’t be so bad if two-thirds of it weren’t eaten up by Pepper Giese’s aimless, self-indulgent, rhapsodically overwritten Tricks of the Labyrinth. No staging could give urgency to this mess of unfocused speechifying as a woman struggles to preserve her independence through her imagination. J.M. Demetrius’s Last of the Dresden Quartet fares better: it has a clumsy charm in Django R. Baker’s spirited staging. Though the story–about three string-musician vampires who sacrifice themselves to the sun–takes too long to reach its silly conclusion and the songs are dreadful, the script exudes a real love for music. Through 5/15: Wed 8 PM, Fri-Sat 10:30 PM, Sun 3 PM. No show Fri 5/6. National Pastime Theater, 4139 N. Broadway, 773-419-5001 or 877-505-6299. $12-$18.
