“it is backlash against a vapid superficial cocaine fueled pop music field”
Superficial, yes, but so’s the rest of rock and roll, almost exclusively. I can discern gradations in quality of musicianship and poetry, but not so as to make it much different than comparing bologna to ham lunchables. It’s all the same crap, mostly. But what fun crap, sometimes.
The one legit Disco band was Chic....Nile Rodgers and Bernard Edwards and Tony Thompson were some of the best musicians around, period.
