No, no bitterness, my friend. I'm an Anthrax fan, though, which means that I'm a Bush fan as well. My bitterness will come to me if a new album would be crappy, or if there wouldn't be any new album at all, and Anthrax will become something like Kiss or Black Sabbath circa '98 and later.
Your "low end" range lack reason is ridiculous. I'm not a musician, but it's obvious that there are quiete a few songs from 90s and WCFYA Joey could manage (with a proper training). There was even a thread on this board discussing Bush-period songs for Joey to sing. And he IS a great singer.
