After performing his next single, "All Day," at the BRIT Awards last week, Kanye West has premiered the single on Hot 97. This is Kanye's third single off his upcoming album, So Help Me God, following "Only One" and "Wolves," featuring Sia and Vic Mensa. An early cut of "All Day" leaked last summer, but the finalized version is much improved, and features Allan Kingdom, Theophilus London, and Paul McCartney. Kanye hasn't said when So Help Me God will be released, only that it will be a surprise, à la Beyoncé and Drake's most recent albums.
Update: March 2nd, 5:50PM: All Day is now available on iTunes.
