I'm not very familiar with Sepultura, I don't even own an album (I intend to buy an album as soon as I get a little money) but through the songs I've heard, and the fans I've chatted with, I've got the impression that Max and Igor Cavalera is Sepulturas 'Arry, the bands backbone. And with both Max and Igor departed, I can't help wonder if Sepultura will survive. Now, for a moment I'll imagine Maiden without 'Arry. Now, I see a band where Adrian and Bruce "controls" the musical guidelines and a band which drifted away from what it is all about. Don't get me wrong, I love their musicwritings but Bruce and Adrian are sometimes a bit too comercial in their musicwriting. And if 'Arry is not there to control it, then it falls apart.
Now, that's about the same situation Sepultura is in now, (am I right?) without the backbone and without the same touch in the songs. Could this band become what it once was in the current situation? I don't think so. Could Maiden be the same or would it be as in my little "fiction" I wrote above?
