While they sold tons of records and the content of their songs grabbed a lot of headlines, there was never enough appreciation for the look of N.W.A. Their late-’80s ensemble of black sweatshirts and Los Angeles sportsgear doesn’t get as much traction as Beatle boots but it is just as iconic. Certainly the group worked because it was comprised of astonishingly talented individuals, but they also looked the part. F. Gary Gray’s new film, which tackles the meteoric rise and enduring impact of N.W.A., also looks the part. That goes a long way in selling this story. Not all the way, but pretty close.
