Dream Widow is the fictional band who loom over Studio 666, the horror comedy starring Foo Fighters. In the film, Dream Widow is a death metal band who all died in an Encino mansion after one of its members became possessed by the devil back in 1993. Foo Fighters move into that very mansion in order to write a new album and history repeats itself, with Dave Grohl becoming possessed by the ghost of the murdering Dream Widow musician. Grohl wrote and recorded an entire EP of Dream Widow music for Studio 666. Most of the instrumental work was by Grohl, but there were contributions from Foo keyboardist Rami Jaffee, keyboardist Oliver Roman, and guitarist Jim Rota. These recordings were issued as an eponymous album in March 2022.
