Corroded Coffin is a band that Eddie Munson is the head of, which also includes his friends from the Hellfire Club; Eddie, Gareth, Jeff, and an unnamed freak. The band has been together presumably for the six years that Eddie Munson has been at Hawkins Highschool. Since he failed senior year twice, that accounts for the six years. They play every Tuesday at The Hideout in Hawkins. At one point, the band also performed for the high school talent show. Eddie invites Crissy to come see him play one Tuesday when they are hanging out in the woods.
