It’s a little hard to believe, but Kanye West has been producing hip-hop tracks now for 20 years. In terms of longevity, he’s been more relevant for a longer period of time than any modern pop producer. And, in that period, he’s undergone several stylistic shifts that have taken him from being a champion of very meat-and-potatoes trad hip-hop — albeit with a chipmunk twist — to being a pop conduit to the outré electronic and old school psych. This article by Third Bridge Creative does a nice job at capturing these shifts, and uses data supplied by Whosampled to back up the analysis. The associated playlist provides a more rote but still compelling look at some of the most recognizable samples, placing Kanye classics next to the originals.
