One explanation is these bands were too monochromatic, failing to stray far from their sub-genres. Instead of taking creative chances and driving the music industry, the music industry drove them out with constantly changing musical tastes. In comparison to classic bands like the Stones, the Who, Zepplin, Deep Purple, who kept expanding their repertoire and stayed on top for decades, metal bands of the early 90's dried up on the vine after a couple of breakout CDS. Where exceptionally talented groups like Slayer and Pantera drove thrash into a wall, Zepplin and other scaled it by incorporating elements of many genres, including progressive, blues, folk, doom, metal.
