Another 'Stranger Things' actor has introduced his band to the world. Joe Keery, who plays Steve Harrington on the hit Netflix show, had a band called Post Animal before filming the show. Finn Wolfhard, who plays Mike Wheeler, is in a band called Calpurnia. Now, Gaten Matarazzo, who plays Dustin, revealed that he's in a six-piece New Jersey band called Work In Progress. The group recently shared a low-quality video to their Instagram of them performing Pearl Jam’s “Porch." Work In Progress is performing in Asbury Park, New Jersey on December 29th, but Matarazzo won’t be there “due to a previous contractual agreement.”
