After Acid Rap, who else but Chance The Rapper would be featured on a song called “LSD”?  ProbCause made it happen, and over a beat that borrows a melody from The Isley Brothers’ “Between The Sheets,” a melody made even more well-known thanks to Biggie’s “Big Poppa,” the two rappers get trippy. ProbCause’s The Recipe Vol. 2 is scheduled for a July 16 release.
