I think Charlie is underrated in the metal drumming world for sure, even though he does still get a lot of respect. For me, he's the best of the Big 4 drummers. I know a lot of people will drop Lombardo or Menza, but I think Charlie takes the cake. Spreading the Disease was the first Anthrax album I bought, and when Gung Ho came on I was like "holy shit!". Also, he writes a lot of Anthrax riffs and is a pretty solid guitar player. He is still going strong at 61 too.
