The Rolling Stones will bring their 50 And Counting tour to the United States on Saturday when the group performs at The Barclays Center in Brooklyn. As with the band’s two gigs at London’s O2 Arena, the Stones have announced appearances by two special guests. Gary Clark Jr. and Mary J. Blige will join the group onstage. Blige also performed with the Stones on November 25 (as did Jeff Beck), while Eric Clapton and Florence Welch guested on November 29.
