Apparently, next week is "free concerts with hip-hop legends week" in Chicago.

We already told you about the Samsung-sponsored Jay-Z show at the House of Blues on Tuesday; now Hennessy gets into the mix with an invitation-only event featuring Common and The Roots (who will also be serving as the house band) at The Shrine on Saturday, September 12. The show will also feature rockers Elevator Fight and Colin Munroe. Want to get on the list? WGCI 107.5FM is giving away tickets this week, and you can also enter to win spots on Hennessy's Facebook page and on www.okayplayer.com.

Make sure to keep an eye out for other upcoming shows on Centerstage's music calendar. Who knows, Nas could announce a free show at Sub-T before the week is out.
