Problem: Post-punk:

Post-punk is a heterogeneous type of rock music that emerged in the wake of the punk movement of the 1970s. Drawing inspiration from elements of punk rock while departing from its musical conventions and wider cultural affiliations, post-punk music was marked by varied, experimentalist sensibilities and its "conceptual assault" on rock tradition. Artists embraced electronic music, black dance styles and the avant-garde, as well as novel recording technology and production techniques. The movement also saw the frequent intersection of music with art and politics, as artists liberally drew on sources such as critical theory, cinema, performance art and modernist literature. Accompanying these musical developments were subcultures that produced visual art, multimedia performances, independent record labels and fanzines in conjunction with the music.

When did post-punk arrive on the scene?
---
A: in the wake of the punk movement of the 1970s
