The sons of Stone Sour and Slipknot vocalist Corey Taylor and Slipknot percussionist M. Shawn “Clown” Crahan have launched their own band. Video footage of singer Griffin Taylor, drummer Simon Crahan and two more unnamed bandmates performing Slipknot’s “The Devil In I” and “Dead Memories” in their rehearsal space has been posted online. Crahan told us a while back that he could envision a time when one of his two sons took over his job in Slipknot. Corey shared a stage with Griffin last July when the younger Taylor, then 14 years old, came onstage to sing Stone Sour’s “Song #3” with his old man. Griffin was born in 2002 to Corey and his first wife, Scarlett. He also has a daughter by a previous relationship. Crahan has four children with his wife Chantal.
