Avenged Sevenfold

The nu metal band Avenged Sevenfold from Hunington beach California started out living up to the nu metal sub genre with their quick guitar riffs and heavy rhythm breakdowns.  The song that gives a good example of this is Unholy Confessions from Waking the Falling.  http://m.youtube.com/watch?v=I-QaFWURsMU.  Next the song Seize the Day from almost five years later.  In this song we aren't hearing the chugging guitar and quick scale runs, here we have gone to a pretty standard pop rock sound.  http://m.youtube.com/watch?v=wheJrsRiuCM. I feel with this kind of change you are taking a big risk of loosing your fan base.
