Meghan Trainor’s “MTrain" Tour pulled into Boston’s Blue Hills Bank Pavilion Thursday night for another sold out hometown show. Much like Trainor’s personality, the show was high energy and upbeat. Since it was Trainor’s hometown show, her family attendance made the night particularly special. Trainor sang her hits “Lips Are Movin’” and “Dear Future Husband” as well as an “All About that Bass” encore that included an explosion of canon confetti into the crowd. She certainly sang with fans in mind as she pulled two crowd members up onstage for a dance party and made her way through the audience. The openers Life of Dillon and Charlie Puth complimented the tour vibe well, and Puth went back onstage to sing his collaboration, “Marvin Gaye,” with Trainor during her set. She demonstrated that her success as a female artist combines a punch of girl power with a dusting of sparkle.
