From groups whose awareness of genealogy spreads wide enough to openly acknowledge Gang of Four's influence (Fugazi, Rage Against the Machine), to those not in touch with their ancestry enough to realize it (rap-metal, some indie rock) - all have appropriated elements of their forefathers' trailblazing contribution. Its vaguely funky rhythmic twitch, its pungent, pointillistic guitar stoccados, and its spoken/shouted vocals have all been picked up by many.
Lyrically, the album was apart from many of the day, and it still is. Though the brilliance of the record thrives on the faster material, it's nearly psychedelic, which is something post-punk and new wave were never known for. Subversive records of any ilk don't get any stronger, influential, or exciting than this.
