king crimson

Almost any classic rock band is best remembered for their classic run, in King Crimson's case, 1969-1974 (although Discipline is of comparable quality and could also be included here). Sure many of these bands including KC released good material later on in their careers, but albums like The Power to Believe, Clockwork Angels, and Mirror to the Sky aren't comparable to Court of the Crimson King, Moving Pictures, Close to the Edge, and other classic masterpieces. Those albums are all timeless classics, anything released later on will at best seen as a nostalgia-fueled comeback that'll just end up forgotten. There might be exceptions but timing is very important. Who knows what people would think of albums like THRAK and The Power to Believe if they had been released in the 70s or early 80s instead of the 1995 and 2003 respectively.

I don't think King Crimson ever released a bad studio album, and of their last three albums, I think THRAK is comparable some to their 70s output in quality (ITWOP, Lizard, and Islands). They managed to evolve their style while retaining their identity (unlike some bands) and I think King Crimson may be more popular now than they ever were in the 70s or 80s.

^ To piggyback off what you are saying I think the rate your music website has helped their popularity since ITCOTCK is in the top ten album list on there. That must carry over on to spotify, youtube etc.
