Singer-songwriter Mike Posner's a hip-hop student turned rock star who's written tracks for the likes of Lil Wayne, Pharrell Williams and Big Sean, as well as Maroon 5 and Justin Bieber. Flashy collaborators and chart-topping dance hits like "Cooler Than Me" aside, he's a sensitive soul who's been dubbed "an introspective pop artist" thanks to spare biographical ballads like "Buried in Detroit" and "I Took a Pill in Ibiza." When Posner hits the stage at the Chicago House of Blues, you'll hear him pour himself into his songs.
