My vote goes to fellow New Yorker, thrasher, great riff & songwriter who is capable of hitting the Spitz/Caggiano era leads - TOMMY VICTOR.
I think he would be a solid fit. Danzig is on/off again as well as Prong. He would be a solid fit for Anthrax. Hopefully he is at least offered an audition.
1-13 Philip H. Anselmo & The Illegals
