Some bands do the opposite: have a smash hit, and then they experiment and innovate and come up with new stuff, and it's difficult to have as large an audience as they did when they were cranking out crowd pleasers and floor fillers.

"Weird Al" Yankovic's "crowd pleasers" are his parodies of popular songs, but he and his band have been playing them to a standard of musicianship that only got better with age; and he has also developed more and more original material that is as innovative as it is a fitting pastiche/homage to other artists.
