Post-punk music emerged in the late 1970s as a reaction to the raw simplicity of punk rock. It incorporated a wider range of influences, including art rock, funk, and electronic music. Artists often experimented with unconventional song structures, instrumentation, and lyrical themes, moving away from the aggressive sound of punk. Key bands in the post-punk movement include Joy Division, Talking Heads, and The Cure. This genre is characterized by its emphasis on atmosphere and mood, often featuring haunting vocals and intricate guitar work. Post-punk laid the groundwork for various subgenres, influencing the development of alternative rock and new wave.
