If you’re a fan of Anthrax, you already know that Scott Ian is a massive horror fan, and that he appearedon The Walking Dead, not once, but twice. So he went from writing about being the walking dude to appearing on The Walking Dead. And it seems like the appreciation works both ways. Currently on tour with Slayer and Death Angel, the band took advantage of their time in Atlanta yesterday, not only visiting the set of the AMC series (which films in Atlanta) before their show at the Tabernacle, but also by inviting star Norman Reedus (or Daryl Dixon on the show) onstage to play bass on “Indians.” It was likely a dream come true for Reedus, and the crowd got a chance to see see a TV star onstage.
