Sure Anthrax might not sell as many records as other new bands, but they haven't even really got the exposure those bands have. Most people when you mention Anthrax to them think of the 80's screaming w/ Joey. I've played some new Anthrax at work and this guy behind me who listens to a bunch of new metal was like, "Damn, who's that? Is that their first album, cause they're good, they're gonna be huge." I tell him it's Anthrax and it's their 8th studio album and he's like, no way. Not a chance. He's a fan of them now.
I want to see Anthrax on a headlining type tour anyway. This new record sounds like it'll kick some ass. And you never know, maybe Sanctuary will push Anthrax out in the open to get played on radio or somewhere, anywhere.
A thrash of the Titans tour would kick ass. Even if Metallica has changed (good or bad, it's everyone's opinion). Put them on a bill w/ Anthrax, Megadeth and Slayer, and they will have to match the intensity of the other 3.
