Stranger Things star Joseph Quinn is making Eddie Munson’s dreams come true.  The actor met Metallica backstage at Lollapalooza in Chicago this weekend, with Netflix sharing a video of the interaction that included a jam session.  Metallica co-founder and lead vocalist James Hetfield said the show was a “bonding experience” for him and his kids, and thanked the actor for doing the song “Master of Puppets” justice on the series.  The rockers also gifted Quinn a replica of his character Eddie Munson’s guitar, which he gratefully accepted.
