No, haven't heard it. Listen to sound clips on itunes, and wasn't too impressed. My friend who is a fan boy loved it, but he would probably love anything they do.
As far as the rant. I don't agree with that being shallow. there are a lot of bands that change their sound. some do it for the better and the fans enjoy it, while others change it in a direction that their fans don't like, but in the process pick up new fans. *shrugs* Take Trivium for example, their new album sounds like old school metallica and I thought it swallowed....now that I think about it, I haven't really enjoyed any of my favorite bands new sounds. It seems to happen when they take too long to put out a new album. Life becomes a bigger factor and the band changes and usually it's a lot softer now that they've been living the good life. From real pain comes the best music. Maybe I am shallow, but if I like a band for a certain sound and that's the role they play in my collection, if they change that sound, they lose their purpose in my collection. On a good note, I think cradle of filth had one of the least disappointing albums this year. Oh, so too did Lamb of God....k, i'm done.
