Killer Mike’s work with the people at Adult Swim is quite lengthy, especially the behind the scenes outfit Williams Street. That single move gave us the first El-P mix with Mike that wound up leading to two El-P albums and more. Now with “The Boonies”, the first leak from the fourth Boondocks mixtape with Alchemist, we’re right back at where we started, the marriage of Mike, Adult Swim & some pretty damn good music. Stream “The Boonies” below and the Boondocks mixtape, in conjunction with the upcoming 4th season arrives on April 16th.
