Second leg will launch Sept. 20 in Boston.

The Rolling Stones will return to North American for another leg of their A Bigger Bang tour, which is destined to be the top-grossing trek in history. The second North American leg, which follows a run of European stadiums, will launch on Sept. 20 at Boston's Gillette Stadium. The dates will be sponsored by RadioShack.

The Stones are the top-grossing band in the world for the first half of 2006, with nearly $150 million in grosses and 1.1 million in attendance, according to Billboard Boxscore. A Bigger Bang is expected to ultimately ring up total box office of more than $400 million.

The band will play primarily stadiums in such markets as New York, Boston, Chicago, Seattle, Los Angeles, Phoenix and Las Vegas. The run includes such non-traditional tour markets as Halifax, Nova Scotia, Missoula, Mont., Regina, Sask., and Boise, Idaho.

Tour promoter Michael Cohl says ticket prices will be about 10-15% less on the upcoming leg, compared to the first, with an additional $20 discount for students. As-yet-unannounced "young, contemporary opening acts" are promised, according to the band.

An American Express presale begins tomorrow (July 26) for some shows. A limited number of Gold Circle seats will be available, while the remaining 90% of the house will average $89 for stadium shows and $99 for arena gigs.

Additionally, 200 fans will have the opportunity to view each show from onstage, as was the case with the first leg. These seats will also be available at the time of the general public on-sale.
