Just out of pure curiosity... KISS

The first, or hotter than hell.  The first album is basically them wishing they were as good as the New York Dolls, while Hotter than Hell is them playing quite a few good tunes influenced by NYDs.  So its up to you.

And in an unrelated item, Kiss was also the turning point where the typical "rock" audience/fan got younger.
For prog, that's happening with some bands like Mars Volta, Tool, where you see teenagers with the T-Shirts. Along with many Extreme/Tech metal bands. The only "old" proggers that I see on these kids t-shirts are groups like Pink Floyd, Rush, Zep, Sabbath. I've seen a few Marillions, and one or two Gentle Giants.
For another example, you could see the metal market skewing younger when Iron Maiden hit it big. Then it was no longer cool to be a 13yr old male still listening to "pop".
SO nowadays, any act with some decent success, short of the avant-garde/jazz scenes seems to get a share (which varies on the genre) of a wider demographic than 30 years ago.
