Every once in a while I’ll dig through some of my favorite hip hop tracks and try and source their samples. 4-Ever Fresh released this acappella version of the rare, 1988 track Urban Sound Surgeon that appears in the Handsome Boy Modeling School classic, Holy Calamity (Bear Witness II). In my half-handed search, I discovered a groovy little website called Who Sampled that breaks down samples from various, and namely classic hip hop tracks. Have a look!
