Picture this—it’s August 26 and you’re on Ravinia’s Lawn enjoying your picnic spread before Lake Street Dive takes the stage when, suddenly, a sweet melody sung by a lovely, yet unfamiliar voice leaps out of the park’s speakers and stops you mid-bite. “Who’s that?” you wonder. It’s Allison Russell. And if you don’t already know this formidable Canadian singer, songwriter, banjoist, and clarinetist from her work with the roots band Po’ Girl, the folk-rock-gospel duo Birds of Chicago, or supergroup Our Native Daughters, meet your new favorite artist.
