Up until the release of 'Out of Our Heads,' the Rolling Stones were primarily known as a group that reworked blues and R&B songs to fit their British background.
The Rolling Stones played the first festival date of their 2015 Zip Code tour at Milwaukee's Summerfest last night, and managed to work in a performance of "Champagne and Reefer" with their old friend — and show opener — Buddy Guy.
