I understand what you are saying very well, and I agree that there were some very good bands making some memorable popular, and even progressive music at that time, but for me, it was also a somewhat sad time, because the explosion of wild creativity that characterized the 1960’s (Jefferson Airplane and Jimi Hendrix are examples) was over. Now it was time to take those design cues, polish and perfect them. That certainly had its good points, but the magic was gone. Periods of spontaneous creativity like what happened in the 1960’s are rare and depend on a confluence of social factors, all of which came together at that time.
Again, not to take away or minimize the early 70’s. There were some very good music created during that time as well.
