Can the Minneapolis Convention Center become a macabre circus of mystery? The dark minds behind the Minneapolis Oddities & Curiosities Expo are going to try their darndest to do so this weekend. You’ll find a mix of weird and wonderful here, including goth tchotchkes like mounted bat bones, sinister terrariums, voodoo dolls, questionable things in jars, and dark art. Taxidermy will abound, and there will even be workshops and classes you can take if you’d like to learn how to preserve dead things. Suspension artists will perform onstage, and tattoo artists will be on hand for those looking to get inked. Find more details at www.odditiesandcuriositiesexpo.com.
