What is the name of Eddie Munson's metal band in season 4 of "Stranger Things"?

Eddie Munson’s metal band in season 4 of "Stranger Things" is called Corroded Coffin. The name fits Eddie’s heavy-metal identity and the deliberately ominous style of Hawkins High School’s Hellfire Club president.

Eddie, played by Joseph Quinn, is a senior student and the leader of the Hellfire Club, the school’s Dungeons & Dragons group. He is also a guitarist and performs metal with Corroded Coffin. Although the band is mostly discussed rather than shown in detail, its name helps establish Eddie as part of Hawkins’ underground metal culture.

Music becomes central to Eddie’s season 4 storyline. In the Upside Down, he and Dustin Henderson use guitars and amplifiers to perform Metallica’s “Master of Puppets,” creating a distraction while the others attack Vecna. The performance became one of the season’s signature moments and introduced many viewers to Eddie’s musical side.

Corroded Coffin is sometimes confused with the Metallica song or with Eddie’s Hellfire Club affiliation, but they are separate: Corroded Coffin is his band, Hellfire Club is the Dungeons & Dragons club he leads. Dio’s Disciples, Iron Serpent, and Rusted Casket are not the band’s canonical names.
