Many thanks for your serious - and polite - replies
That seems an uncontroversial observation to me - PiL and Joydiv were easily the most prominent and influential groups. Joy Div were widely imitated, PiL less so cos actually quite hard to copy, but Johnny L's and Wobble's line of patter had a big effect.
Who else was more influential or seen as pointing to a right path?
PiL were big because of Lydon, whose status came from the Pistols, and people followed him into PiL. (I
rushed to Virgin Nottingham to buy the first single when it came out.) Joy Division weren't so very big until
after Ian topped himself.
It's only circumstantial evidence but if you look at Peel's Festive 50s at the time:
1979 is still mostly filled with punk favourites, but the post punk bands coming through are: PiL, Magazine, Gang of Four, Tubeway Army, The Fall, The Cure. Whereas Joy Division don't figure at all, even though
Unknown Pleasures and
Transmission both came out that year.
1980, on the other hand, post Ian's death, and Joy Division suddenly dominate.
Also, I'm not sure either PiL or Joy Division
were particularly influential back then, not in the sense of spawning copyist bands. The whole ethos of post punk was doing whatever you wanted. The right path, such as it existed, was
not to sound like anyone else. Added to which, things were still localized in scenes in various cities (and around different labels) in Manchester, Birmingham, Edinburgh, Liverpool, Leeds, Sheffield, Bristol, as you rightly portray in your book, with more than one scene in London. It was only the rise of indie that saw certain styles becoming established, and from bands like the Bunnymen, Teardrop Explodes, Bauhaus, Orange Juice...
Re less-is-more indoctrination in the Wire.
That's based on my memory of the era and the experience of actually feeling revulsion when I heard a guitar solo
If that's your own experience, fine, of course. It's the "we were all" that I took exception to. Speak for yourself

. We (also born 1963/64) were listening to all sorts of stuff, including guitarists like Robert Fripp (with Eno), Dave Gilmour (with Pink Floyd), Jimi Hendrix, Fred Frith (with Henry Cow), and so on. And Joy Division had screaming guitar solos too. Go to 2:45 on this:
Yes, virtuosic guitar wank was certainly non grata in post punk. That attitude came from punk and no one was going to go back to doing that. They'd just have been laughed at anyway, even if they did have the chops (which, as you say, they mostly didn't). But that wasn't less-is-more as a
policy. There was plenty of "more" in post punk. It was rather: why would anyone want a ridiculous guitar solo in a post punk context? Where would it go?
Yes, I've read and heard Andy Gill on his guitar playing. But
Solid Gold – if you count that as later? – isn't a change in that. The guitar on the
Damaged Goods EP is much the same; for example:
It's
Entertainment that's the outlier there (and I've never liked that album myself). The substantial move came when Dave Allen left and they attempted a more commercial sound.
Obviously the main reaction against guitars came with the synth bands.
No, I've never much liked Prince either, though that had (and has) nothing to do with his considerable technical skills as a musician.
PS (edit): Nor have I ever before thought of Tom Verlaine's solo on
Marquee Moon as "unmistakably a spiritualised version of arousal and ejaculation", and I hope never to think of it in that way ever again.
