Kanye Performs at Facebook Headquarters

Kanye West swung by the Facebook offices in Palo Alto, California yesterday to perform acapella versions of some new tracks off his upcoming untitled album.

He performed the following never heard before songs, "Mama's Boyfriend," "Chain Heavy," and "Lost in the World."

His verses are pretty hard hitting and the fact that he performed them acapella builds more anticipation for his album.  This was a great marketing move by Kanye to  leak new music in a way that's never been done before.

Not to mention that he was at Facebook Headquarters, which is very random but then again it is Kanye we're talking about here.

Check out the three different videos below.
