In the late '90s, the French group Air released Moon Safari, and the mostly instrumental album became an unlikely hit. Last year, Air celebrated the 25th anniversary of Moon Safari by reissuing the record in a deluxe audio-video package and playing the album in its entirety for the first time during 77 shows across Europe, North America, Australia, Latin America and Asia. That tour has been extended, and it brings the group to MGM Northfield Park — Center Stage. The show begins at 7 p.m.
