Why NPR’s Ari Shapiro won’t sing on the air — but will in St. Louis this weekend

As a host of NPR’s “All Things Considered,” Ari Shapiro moves easily between breaking news and delightfully quirky stories. When he’s off the air, he performs cabaret. This Saturday, he brings his solo show to St. Louis City Winery. Shapiro talks about the performance, how he balances his artistic and journalistic sides — and why he was once banned from playing the tambourine on stage.
