It may not be the usual Citizens Bank Opera House fare, yet the upcoming appearance on April 30 at 7:30 p.m. by our nation’s most prominent power couple should prove just as mesmerizing as any musical or ballet. Billed as An Evening with President Bill Clinton and former Secretary of State Hillary Rodham Clinton, this night of conversation promises insight into their years in the White House as well as their subsequent ventures, including Hillary’s time in the U.S. Senate, in President Obama’s cabinet and her bid for president. And who knows? Perhaps Hillary will reminisce about her time as a college student in the Boston area. If you don’t mind a background check by the Secret Service, VIP Meet & Greet packages were still available as of press time. For tickets, visit ticketmaster.com or call 800-877-7575.
