The Bruce Springsteen Land of Hope and Dreams American Tour opener on Tuesday, March 31 rock the Target Center in Minneapolis and apparently the White House, too.

“The tour is going to be political and very topical about what’s going on in the country,” Springsteen said last week, describing the tour to The Minnesota Star Tribune.
