For the second year in a row, Stoli and Neumos are teaming up to present a free Halloween extravaganza, which will climax with a performance by Champagne Champagne (who also headlined last year’s event). At press time, Champagne’s DJ Gajamagic told me that he, Thomas Gray, and Pearl Dragon were debating between dressing up as Teenage Mutant Ninja Turtles or “Mario Brothas,” and that, Halloween partying aside, people should show up just to hear some brand-new material—“newer than the other new stuff, like just-made-them-this-week new.” If that’s not enough incentive, the bash will also feature zombie strippers, a screaming contest, and what’s being billed as a “Baby Toss.” Neumos’ Jason Lajeunesse declined to give me any further details about that particular activity, instead giving me the plot-thickening response, “I can’t give you any more info than that. That is it. But there will be a baby toss……trust!” In true Halloween spirit, I don’t know whether to be intrigued or frightened. With Sean Cee, Zeta Barber, Chocolate Chuck. ERIN K. THOMPSON
