The thing with Chicago is, there’s always more than meets the eye. In the case of Carroll Avenue, beneath the Kinzie Railroad Bridge, we mean that quite literally. This underground street is a relic of the heyday of the railroads. Today, it’s a well-kept secret, often used by bands to discreetly exit the House of Blues. Forget GPS, here instructions and address markers are only marked in graffiti. This style reminds us of Carroll Avenue, look closely at the details of the rich acetates and you’ll start to see its depth.
