Finally, a new album. It doesn't surprise me they're going with a slightly different sound. They said the same thing for The Open Door, and Amy has said she never likes to produce the same types of albums twice.
I'm excited for a new album, though I still need to pick up Green Day and Breaking Benjamin's newest albums as well.
In a way, Amy IS Evanescence, but the differences were noticable in the rest of the band from album to album. I think that in a way, the lead singer does make the band, but there are some band members, like Eddie Van Halen, that make the band. Some people don't think Nightwish is Nightwish anymore without Tarja on vocals, but I only own their latest album with Annette as the singer.
