The Minnesota Fringe Festival, the largest in the U.S., is halfway through its 10-day run, and Dylan Hicks detects some subtle shifts in the focus of many participants. “With more shows than ever, the Fringe serves as a broader – if still skewed – zeitgeist-o-meter. In keeping with the tenor of the times, frivolity is somewhat on the wane. In terms of percentages, there appears to be a decline in shows trumpeting nudity, and while comedy remains strong, it’s not quite the hegemony it once was. Either that or it’s just lurking in odd places.”
