Christina Perri played a sold-out show at the Neptune Theatre on Saturday. It was one of the last stops on her Head or Heart Tour which supported her recently released sophomore album with the same name. Backed by her four-member band, the charismatic and witty Perri had a great intro to every song. Near the end of the set, Perri asked the audience to take selfies, post them on her website and she would select her favorite. English songstress Birdy opened (complete set of photos to follow).
