What fictional band name did Grohl use for the Studio 666 metal EP?

The fictional band name Grohl used for the Studio 666 metal EP was Dream Widow.

Dream Widow is the satanic heavy-metal group whose unfinished recordings drive the supernatural plot of Studio 666, the Foo Fighters’ 2022 comedy-horror film. In the story, the band recorded at the same cursed mansion later occupied by Foo Fighters.

Outside the film, Dave Grohl created and recorded much of Dream Widow’s music, with contributions from guitarist James A. Rota II and other musicians. The project was released under the Foo Fighters name in 2022 and is often described as an album rather than strictly an EP; the terminology can vary because the initial project was presented as a short film-related metal release.

Dream Widow is easy to confuse with Grohl’s other projects. Probot was his heavy-metal collaboration with guest vocalists, while Dee Gees was the disco-themed Foo Fighters alter ego used for Hail Satin. Neither name belongs to the fictional band in Studio 666.
