Gang Starr (RIP Guru) have been one of my favourite rap troops for a long while, but my love for them grew even more when I heard that they sampled Marlena Shaw. "California Soul" was actually originally performed by The Fifth Dimension and then covered by Marvin Gaye & Tammi Terrell (Woah! Quadruple Dip!). Gang Starr use the Marlena Shaw version...probably because it's the best one. Check their technique, Marlena would be proud.
