do Anthrax still play classics Live?

They usually play Among the Living. Caught In a Mosh. And other classics.
It depends on how long they're on stage.
They played "Be All End All" and "Metal Thrashing Mad" during the Killer A's tour.
John Bush is the best metal vocalist around.
 
"Caught In A Mosh" is the lone staple from those 2 albums. But they almost always play at least 2 songs from ATL. "Among," "Indians," "I Am The Law" and "NFL" are all possible. They have been opening w/ "ATL" since 2000, and were playing an abbreviated version of it as far back as 1996, so I won't be surprised if it is dropped. "AIR" and "Madhouse" are the two most consistently appearing Disease tracks. No gaurantee on either. They also played an abbreviated portion of "Armed and Dangerous" during the "old school/time machine" medley in 1998. "Gung Ho" made a brief comeback in the set as an encore on 3 or 4 headline shows in 2001 before the tragedy of 09/11.
 
"Gung Ho" being dropped had nothing to do w/ 09/11. It just so happened that Anthrax were doing a weeks worth of headline shows in early September of '01 before hooking up w/ Priest. And at those shows, they played "Gung Ho", they also played "Random Acts of Senseless Violence" and they were opening w/ "Bring The Noise" When 09/11 happened, Anthrax turned the bus around and went home. And when they went back out in '02, they weren't doing any of the above things any longer. Hopefully all 3 come back for the new tour.
