Hi
@-Asdfgh- ,
Just curious, I know a couple, but which musicians are you referring to?
"Officially" at least - if you can use that word with punk, prog rock was the antithesis of punk... even Matlock's [Sex Pistols] bass lines were considered too complex by Rotten... (listen to the demo tapes [Spunk/This Is Crap] some excellent bass lines on those, missing on the NMtB LP, regardless who actually played them on that album). But especially Jerry Dammers (The Specials) certainly wanted to move much further in that direction with the Specials & did later rather extremely on his own. Though part of the scene in NYC, the Talking Heads never considered themselves Punk, more Art Rock especially after Eno became involved with More Songs About Buildings & Food. Art Rock is more or less synonymous with Prog Rock perhaps minus the symphonic influence (which not all "Prog Rock" stamped bands had). They certainly were not 3 minute Radio ditties about romantic love, but none the less very danceable

. Even Fripp's League of Gentlemen (Sara Lee on bass) while perhaps a bit too far out there for many, was danceable, albeit in a more punk manner

.
=> "The issue is labelling to some extent as few artists keep to a narrow genre even for one album."
+1, as always. Such containers never really fit for most, we as humans like to stick things in confined drawers, put black & white labels on them and ignore the bleeding & complex full color spectrum of life/reality with most everything unfortunately. They can be helpful sometimes, but only as long as we remember they are very imprecise.
