Would the post-punk era be called "New Wave"? Are those synonymous terms?
A collection of movements. New Wave, New Romantic, Goth/Alternative
Many people might use the synonymously. But not all. New Wave would be considered more accessible or pop related. Post Punk was more Avant-Garde and dissonant, including No Wave.
No.
It would be the start of Electronic music. Keyboards. The band post-Ian’s suicide INVENTED synthesizers. There were really NO synthesizers around in 1979 that were being played properly. Another amazing fact are the lyrics side of the band. And do not get me started on the publishing side, Fantasy Records and the best music dance club in the entire World -— located in Manchester, England. An incredible story, how they LOST MONEY on the BIGGEST 12” record/song ever published, and a song still being played today in every major city on the planet. Too bad they are libtards.
