"Wolves" was produced by West, Cashmere Cat, and Sinjin Hawke and was originally planned to be the opening track to The Life of Pablo. West debuted the song on February 12, 2015, at a fashion show where he also premiered his new Adidas shoe.^[1] The presentation was broadcast live to more than 40 locations around the world.^[2][3] "Wolves" became the second confirmed track from the album^[4][5] and originally featured Sia and Vic Mensa. The initial album version introduced a new verse from West and an additional outro from Frank Ocean, omitting Sia and Vic Mensa's contributions. However, in March 2016, the album was updated with a new version of the song that reinstated Sia and Vic Mensa's verses. Frank Ocean's outro has been split into a separate track, titled "Frank's Track", which appears after "Wolves" on the track list. The song was used in the trailer for the Netflix crime drama series Ozark.^[6] The song received widespread acclaim from music critics. - Wikipedia
