AEROSMITH will be performing in Boston's famed Fenway Park on Saturday August 14 with THE J. GEILS BAND in what will surely be the ultimate must-see show of the summer. AEROSMITH and THE J. GEILS BAND, two of the world's hardest-rocking bands who call Boston their home, will play together at Fenway Park. This promises to be one of the most important shows in rock and roll history.The announcement of the "Double Play" event was made Wednesday evening (April 7) by Boston home boys Steven Tyler and Peter Wolf at the top of the 4th inning of the Red Sox/Yankees game when they visited Red Sox announcers Don Orsini and Jerry Remy to make the surprise announcement to a roaring Boston crowd. This is the first time both bands have ever played together. "Sox fans, look out! You've got a grand slam with AEROSMITH and J. GEILS and we're going to rock it over the Green Monster," said Steven Tyler. Tyler most recently appeared at Fenway Park for the opening Red Sox/Yankees game on Sunday, April 4 when he performed "God Bless America" from the field. AEROSMITH's Joe Perry, who is currently on tour in the U.K. with THE JOE PERRY PROJECT, commented from Newcastle, England, "When I heard that AEROSMITH would be playing Fenway Park this summer, naturally I freaked out. Then I heard it was going to be with THE J. GEILS BAND. I knew that this is an event that I, like all hard core Bostonians, have been waiting for for 40 years. There have been other shows at Fenway Park, but this one is going to leave them all behind because it's going to rock so hard the Green Monster will crack and they will have to keep the Citgo sign together with duct tape and glue. The biggest problem for me is that I can't be on stage and in the audience at the same time. I'll definitely be in the audience watching J. GEILS' performance." AEROSMITH, the biggest, most enduring and thrilling band in rock history will make a spectacular return to South America for the first time since 2007 beginning in Caracas, Venezuela on May 17 with the "Cocked, Locked, Ready To Rock Tour!" The band will then go to Europe for 11 more knockout shows. AEROSMITH will be celebrating its 40th anniversary later this year. For more than 30 years AEROSMITH has defined American rock and roll. They've earned countless awards (including four Grammy Awards, eight American Music Awards, six Billboard Awards, and 12 MTV Awards), performed electrifying sold-out concerts around the world, and have a fan-base numbering in the millions worldwide. Tickets will go on sale Saturday, April 17 through LiveNation.com and by phone at 1-800-514-3849. Tickets will not be available at the Red Sox ticket office.
