They had been sending tracks back in forth, and were in the early stages of developing songs, soon to be in the studio.
Such haters. Corey Taylor would have rocked as Anthrax's singer. The guy is a damn good singer, much better than Dan Nelson, and could have given a big name to a once-big band again.
Instead, Anthrax screwed up with Dan Nelson, damaged its image, had to call on John Bush to bail them out, and now go with their tail between their legs to Joey Belladonna as their second choice. And now they are stuck with a singer that makes them very 1980s again. Try thinking about Joey singing "What Doesn't Die" or anything from the Bush era. Not going to be good.
That was the beauty of Corey. Like Bush, he could sing Bush's material AND Joey's. Good luck with Joey being able to do both eras.
