Norman Reedus Comes Alive At Anthrax Show

Exclusive Video

Norman Reedus ditched his crossbow for a bass guitar to join Anthrax onstage and get his thrash on. 

"The Walking Dead" star was at Atlanta's Tabernacle Wednesday night to blow off some steam with the metal band -- he's in town shooting his popular zombie show -- and they invited him to play along with bassist Frank Bello for their song "Indians."

Check out the vid ... Norman doesn't need to be in Daryl Dixon mode to slay.

This isn't the first time Anthrax and 'TWD' have been connected, either ... guitarist Scott Ian put on some gruesome makeup to play a walker in a season 5 episode. He got offed.
