The movement (as such) is definitely still there, but by its very nature of being progressive it moves with the times. It may well have moved in the direction of punk but at the same time it broke off into several new forms coinciding with the commercial release of the 'easier to work with' digital synthesiser - itself surely not a coincidence.
i.e. Joy Division became New Order became Electronic (to a degree). That would have been a ground of influence for a massive variety of synth based bands and also an influence over change of direction for more conventional bands to produce a change of style (think Chicago - massive style change over the course of their recording life).
Then there's stuff like The Alan Parsons Project which peaked far later then 1975, a group in its own right but of course still working with mainstays like Pink Floyd and doing a heck of a lot of behind the scenes production on other great outfits.
I'm not sure if I'm right here, but I always felt that Supertramp were a major progressive rock band. They moved so well with the times, utilising new instruments and techniques but always retained their unique elements; multiple changes in tempo, excellent organ hooks, shouting in the background etc etc. They must have had an influence on far more bands than they'll ever receive credit for.
Andre will love this thread!
