"Black Lip Bastard" was one of the first new joints we heard from Ab-Soul earlier this year, though for whatever reason he decided to leave it off his upcoming Control System album. Sort of. Rather than just put the original track on there, he got his Black Hippy cohorts to hop on the soulful beat. Now, you can hear Ab spitting alongside Kendrick Lamar, ScHoolboy Q, and Jay Rock on the closing track to Control System, which drops tomorrow (May 11). Listen below.
