Kanye West made a surprise appearance on Los Angeles radio Friday morning to premiere the still-untitled first single from G.O.O.D. Music's upcoming Cruel Winter. The brooding, synth-heavy track, which debuted on Big Boy in the Morning, features an all-star array of guests on the track, including 2 Chainz, Migos' Quavo, Big Sean, Travis Scott, Desiigner, Yo Gotti and the freshly sprung Gucci Mane. Neither Cruel Winter or its new single have set a release date; West admitted that the track will undergo more mixing before its official release. The rapper also revealed during the interview that Cruel Winter will feature a 15-minute version of Desiigner's "Panda" that includes a verse from every rapper on the G.O.O.D. roster.
