When: August 5, 2011

What happened: This is where it all begins. Just ten days before Chief Keef turns 16, his go-to director, DGainz, uploads the video for "Bang," which also happens to be the rapper's favorite ad lib. Produced by DJ Kenn, the track is more left-field than some of Keef's later work, but it quickly becomes one of his most popular tracks. Washed with a hazy green filter, the visuals depict Keef wearing a bucket hat, rapping alongside his friends (including Lil Durk and Sasha Go Hard), and making trigger-pulling gestures toward the camera. A star is born.
