Ice Cube is a worshipped deity to rappers with grit in their voices and righteous anger in their hearts. Would Killer Mike have been inspired to cut “Reagan,” his brutal smackdown of the 40th U.S. President, had Cube not been around to depict the stark reality of Reaganomics from the front lines? His passion was often scored by bass-heavy G-funk beats, which his Los Angeles descendent Kendrick Lamar nods to on tracks like “King Kunta.”
