Kanye West debuted a new song last night at 1 OAK nightclub in Las Vegas, where Yo Gotti was holding his The Art of Hustle album release party. He prefaced this debut by going on a 9-minute rant about Taylor Swift, TIDAL, the media, and other topics.

The song features British crooner Sampha, best known in rap circles for singing on Drake's "Too Much." According to the YouTube video, it is entitled "Closest Thing to Einstein." According to one Reddit post, it's called "Night Sky." 

Kanye raps about his now-patented Twitter rants -- "People try to say I'm going crazy on Twitter/ My friends' best advice was to stay low" -- which is ironic, because shortly before debuting this song, he went off on a Twitter tirade against music producer Bob Ezrin.
