Our good friends at Grappa Frisbee have a podcast series called Grappadiggin and for their ninth instalment, they asked DarkoTheSuper a.k.a. Doc Heller to throw down a collection of underground raps and beats weighing in at just over ninety minutes. We’re talking joints from the likes of Blu (& Exile), Das Racist, Earl Sweatshirt, Madvillain, even some Frank Zappa & The Mothers Of Invention! Of course, the Doc drops some of his own beats in there as well.
