There’s been a lot of buzz about the Stones lately, especially with the release of GRRR! and their “50 and Counting” tour to celebrate the group’s 50th anniversary. The Stones have already kicked off the first of their anniversary shows at London’s O2 Arena. Former Stones Mick Taylor and Bill Wyman appeared, along with R&B star Mary J. Blige. Eric Clapton and Florence Welch also joined the show as guest performers at the second London show. The Stones are headed to the U.S. for their first show at Brooklyn’s new Barclays Center on December 8th. The band will be joined by Blige again, as well as rising star and Elmore favorite Gary Clark, Jr. They’ll be following that up with two performances at Newark’s Prudential Center on December 13th and 15th.
