Often wrongly touted as a weapons of mass destruction, anthrax is in fact used as a 'weapon of mass death', as it causes very little destruction, and lots of death.
"Anthrax killed several thousand people today, but caused little destruction."

Kick-ass 80's metal band, rhythm guitarist Scott Ian is probably the best known member.

One of the 'big four' of thrash metal: the others being Megadeth, Metallica and Slayer.

Contrary to 'ash's definition, the original vocalist for their 1st album (Fistful of Metal) was Neil Turbin, who left soon after to pursue a solo career.

The majority of people agree that Joey Belladonna was the best singer (Armed and Dangerous - Persistance of Time ERA) , and the rcent reunion is the best thing since... when he was in it before.
I went to see Anthrax play at Rock City the other week, they only played their old stuff, it was totally awesome.
