The Rolling Stones have kept things busy this week with a new rash of rumors and announcements. The juiciest, of course, is a report that the group will commemorate its 50th anniversary with two shows each at the O2 Arena in London and the Barclays Center in Brooklyn for $25 million. The shows -- the band's first since October 6, 2006 -- are said to be promoted by British entrepreneur Richard Branson and Australian concert promoter Paul Dainty rather than the Stones' longtime Toronto-based promoter Michael Cohl. The group has made no official comment about the report. The Stones did, however, announce that "Crossfire Hurricane," the 50th anniversary documentary by director Brett Morgan, will debut on November 15 on HBO, while its 1973 concert in Belgium, "Brussels Affair," will be released in three limited edition vinyl box sets prices $750-$1,500, with pre-orders being taken at the Stones' official web site. The group's "Rolling Stones 50" photo book is due out in the U.S. during October, while a 50th anniversary box set is also expected this fall with two brand new songs recently recorded with Detroit-born producer Don Was at Guillaume Tell Studios in Paris.
