My introduction to Michael Shannon was his portrayal of Kim Fowley (their creepy manager) in the Runaways movie. Since then, I’ve seen him in Boardwalk Empire and the George Jones mini-series. He’s even done a tour of REM’s Murmur album and Chronic Town EP with some of the REM guys joining him onstage.
Kind of a tangent, but happy that my interest in Joan led me to his acting. One of the first songs I learned on electric guitar was her I Love Rock and Roll and I’ve become friends with one of the original Blackhearts, ie. Eric Ambel (Del Lords, Yahoos, etc.).
