A lot has changed in the two years since Mac Miller’s last album Watching Movies with the Sound Off. The Pittsburgh rapper left his independent label Rostrum Records and signed a reported $10 million deal with Warner Bros., where he will release his major-label debut GO:OD AM.

The 17-track set is now available for pre-order on iTunes and includes the single “100 Grandkids,” for which he has released a video. In the imaginative clip, Mac stars as the moon in a children’s play, while rapping about promises he made to his mother and living out his dreams. Halfway through, it switches up as he performs in front of a lowrider and reflects on his first 100 grand.

GO:OD AM is done and will drop Sept. 18. It took two-and-a-half years and nine albums worth of material, but he considers it his best work yet.

In support of the album, he will play a series of release shows called “A Night with Mac Miller,” kicking off Sept. 20 in his hometown. A full tour will be announced on Aug. 17.
