Following last year's Faces mixtape, Mac Miller returns with GO:OD AM on September 18th. The album features "100 Grandkids," which Miller performed last week for fans at the Grassroots Festival in Omaha. Today, Mac Miller has released the video for the track, starring himself playing a fixture in an elementary school play. The video, directed by Nick Walker, comes as part of a larger announcement from Miller that includes a pre-order for the album as well as a slew of tour dates starting with Miller's home of Pittsburgh on September 20th.
