Heh, not really sure matured is the proper word
. That album, while I enjoy some of the songs, seems more contrived than anthying else. To me, Weathered was made to make money, and the guys have even said it was a bit rushed. My guess is, Wind-Up/JHMP had a lot more of a hand in the sound than Creed would have liked because they wanted to milk the cash cow as long as they could. Hence the ridiculous touring scheduled during Weathered. BearFan is right, I think Weathered's success rode the coattails of Human Clay.
Not all musicians have that same attitude. Some of the ones I like have been quoted as saying something to the effect of: Here's our music; if you like it, great, if not, tough shit. Most of those artists make better music, IMO, because they at least try to stay true to themselves and create from the heart.
