While some Chicago students are leisurely wasting their days with less-than-profitable pursuits of skateboards and video games, others are meticulously planning their future and running modest businesses on the side. And this is thanks in part to hometown hip-hop hero Common, whose concert at the House of Blues on Saturday helps benefit his own Common Ground Foundation as well as NFTE Chicago, a nonprofit that helps Chicago youth create individual business plans and start their own financial ventures. “They can range from web design to catering,” says NFTE Chicago Executive Director Christine Poorman of the kids’ up-start businesses. “A lot of the kids are doing something to do with the music industry. A lot of them are interested in hip-hop, which is the exciting connection of having Common at the show.” The doors open at 6pm for the sold-out show, with support from Office, Reese and DJ Ken.
