re: Most Misunderstood or Poorly Received Great Album

what planet do you guys live on with these?

Outside nick drake, all of these were huge hits commercially. They might have gotten panned but they were commercial successes.

Television Marquee Moon was a commercial flop but is considered one of hte highlights of the 70s these days.

Suicide's suicide is hugely influential but hardly any notice until 10 years later.

You might be able to add Galaxy 500 On fire to this list too. And maybe Spaceman 3's perfect prescription, although that was a modest success.
