Sarah Silverman, The Band Perry Headlining Largest New England Benefit Concert for Wounded Soldiers

The country band and big-time funny lady will be at Symphony Hall with a load of other celebs to raise funds for Iraq and Afghanistan veterans battling PTSD.

The Red Sox Foundation and Massachusetts General Hospital Home Base Program announced they are organizing a benefit event titled Mission Gratitude, a concert that will raise funds to heal Iraq and Afghanistan veterans and their families from the “invisible wounds” of war—referring to post-traumatic stress disorder and traumatic brain injuries. Mission Gratitude is the largest benefit concert in New England supporting wounded soldiers.

Mission Gratitude will be held on September 23 at Symphony Hall, and several big artists and performers will help raise these funds for soldiers. Performers include comedienne Sarah Silverman, country artists The Band Perry, Big & Rich, and The Henningsens, Saturday Night Live alum Darrell Hammond, The Voice season 3 winner Cassadee Pope, recording artist Angie Johnson, and singer Rita Wilson. And of course, what’s a party in Boston without some Boston legends? Previous Red Sox pitchers Pedro Martinez and Tim Wakefield will also make appearances.

The Red Sox Foundation and Massachusetts General Hospital Home Base Program works to help Iraq and Afghanistan veterans and their families (including spouses, children, parents, siblings, and significant others) recover from post-traumatic stress, deployment stress, and traumatic brain injury. Home Base serves active duty, Guard, Reserve and out-of-uniform veterans throughout New England. The program also serves to help every veteran regardless of their discharge status or insurance.

An online auction will be open from September 3 through September 30, in addition to the concert, at biddingforgood.com/mgh. All proceeds from the concert and auction will benefit the Home Base Program.

Mission Gratitude takes place September 23 at Symphony Hall, 301 Massachusetts Ave. For more information, visit missiongratitude.com.
