NEW MUSIC: Chief Keef ft. Lil Durk -- "Gotta Sack"

Chicago homies Chief Keef and Lil Durk join forces on the Young Chop-produced "Gotta Sacks." The track is the first collaboration between the GBE and OTF rappers.

“We all the same. Only The Family and Glory Boyz Entertainment, " Lil Durk, who has a record deal with Def Jam, told Complex recently. "Everybody’s family with two different names. Everybody says GBE and OTF. Everybody grew up together from the same block. Everybody knew each other since they were kids. We grew up with each other and everyone’s just got different music styles right now, doing their own thing."
