Bands or artists who released great albums long after their "classic" period had ended

Artists that continue to produce records for many years tend to have a life cycle, where you have an early period, generally before they hit it big, when their sound was often raw or even in some cases very different than what they ultimately became known for, a classic period where they released most/all of the records that made them famous, and then (if they didn't break up) a post-classic period where they may have continued to release albums, but rarely anything that caught public attention like their classic stuff. What I'm looking for is, what bands or artists out there do you think released some of their best work during their post-classic period?

I'll offer two: Hawkwind and King Crimson.

Hawkwind's overall best album is, I think, 1975's Warrior on the Edge of Time, but right behind it I would put 1992's Electric Tepee.

King Crimson is obviously best known for 1969's In the Court of the Crimson King, but I prefer 2003's The Power to Believe. There is some truly phenomenal guitar work on that album.
