Who says good things never happen on a bus? 

Super producer Metro Boomin recently shared a video of himself sitting in a bus and blasting some new 21 Savage music. The track is presumably produced by Metro himself, and 21 Savage fans will be pleased to note that it goes hard. Metro is clearly feelin' himself here, vibing to his handiwork while the young gentleman sitting behind him contemplates the nature of his existence. 

Metro and 21 Savage have previously collaborated on the Savage Mode EP. As for the song in question, we're not sure where it will eventually end up, but Savage's upcoming Issa Album would be an educated guess.
