“Rock Music” folds rock, pop, and club music together in a way that post-punk has done for 50 years. Mimi Haddon’s book What Was Post-Punk? argues that that the thing that sets post-punk apart from other rock scenes or styles is not its temporality or “post-”ness, but its incorporation of “alternative” styles of Black music -- disco and reggae -- rather than the blues. Acts like Gang of Four or The Slits are clear examples of this. Before Nevermind’s crossover success promulgated the mistaken view that modern rock/alt rock was mainly guitar-driven music, acts like The B-52s and The Pet Shop Boys routinely had crossover pop hits on both the US and UK charts. Not only are the lines between rock, pop, and club music historically much blurrier than they are presented in the Jacobin article
