Out of curiousity, if you were asked if Jim Florentine or Austrian Death Machine would be signed by Metal Blade, would you assume they would? Furthermore, The Goo Goo Dolls used to be on Metal Blade. Not to say that Attack Attack! is anything compared to any of them, but sometimes signings that don't make much sense just happen. Ask Limp Bizkit. Furthermore, why would they have to be Christian to sign to Ferret? Thats not a Christian label. Never has been.
Metallica was briefly on there too
