I mean, at the end of the day, it's literally referring to a new wave of British music being popularized in the united states, and like the 60s, it's not even remotely close to one similar sound. And of course artists like Blondie, The Bangles, the GoGos and take your pick of whatever other LA acts aren't even British.
To me, New Wave is an easier way of saying, "80s music....but also late 70s music....but not metal."
Er, not quite for the start (I was there for the whole thing in NYC).
.
It started with Punk in NYC - the original CBGB's Bands (who some also played at Max's Kansas City).
Television, The Patti Smith Group, Talking Heads, The Ramones, Richard Hell and The Void Oids, Blondie (think I got everyone)
Now the sound of these bands were often rather different from each other; but they were DIY simple sets of instruments, not all fancier upped like Progressive Rock.
Punk magazine, and not too long after New York Rocker we're published. The word began to get out!
They started to tour around in the USA, Britain, and Europe. Malcom McClarin in England I believe after seeing The Ramones decided to put together The Sex Pistols, while I believe The Clash formed more organically. Susie & The Banshees, and more.
I think the term New Wave
might have been coined to 1) maybe soften the perhaps the "edginess" of the term Punk 2) the sound of bands after these initial ones maaaybe were a bit less raw than the Ramones, The Sex Pistols etc
We then had The B-52's, Tom Petty & The Heartbreakers, Devo, Tears for Fears etc
There was "No Wave" Sonic Youth.
This started in the mid-70's and expanded through the '80's. Television influenced The Edge, Patti Smith took time to talk to a very young Larry Mullen Jr when they toured over there in Britain etc.
While I didn't know every song on many of those album listed (and none of the Eastern European ones) I knew most of the albums shown.
I had a big smile looking over it.
From '74-'75 into the mid+ '80's
was a great time to be a music fan! I had a
fantastic time - radio, vynil casettes, and
live shows!!!
Not only then (going forward) the ?early - mid '00's was another big out pouring of talent.
