Kanye West stopped by the Facebook offices to perform some of the songs off of his untitled upcoming album currently slated for a September 14 release. 

Choosing to take an a cappella approach, West stood alone on a table in a crowded conference room dressed in a tailored suit, and belted out three new songs -  the comical “Lost in this World,” the contemplative “Chain Heavy” and the tribute to his late mother Donda West “Mama’s Boyfriend.”

Here’s “Lost in this World” with the other 2 clips below the fold.
