“911 / Mr. Lonely” is a two part track released as a single along with “Who Dat Boy” on June 30th, 2017. The song is the 10th track on Flower Boy, and features Frank Ocean, Steve Lacy, A$AP Rocky, ScHoolboy Q and Anna of the North. The first half is more upbeat but is filled with dark depressing lyrics. The second half has more depressing lyrics, but with a less upbeat and snare heavy beat. The song was one of the stand-out tracks of Tyler’s critically acclaimed fourth album, Flower Boy.

The beat used in 911 was originally used in Tyler’s 2016 GOLF Fashion Show with further instrumentals and vocals being added and changed.

This song might come as a shock to many fans of Tyler. During the release of Cherry Bomb he stated that he is not depressed anymore and that he wished to ditch “depressing rap”. Because of his transition of rapping about dark, violent and depressing topics to rapping about cars and wealth, Tyler was often criticized by fans of his older material – like Bastard and Goblin. When it comes to content, mood and lyrics, this is more in line with his previous material.
