Dream Widow is a fictional band, created as an alter ego for the Foo Fighters. In preparation for the release of Foo Fighters’ first ever feature film, Studio 666, the band has taken on an alter ego in the form of a blackened thrash collective and the result is a ferocious new single titled, “March of the Insane”. The track is integral to the plot line of the film in that the song ended up being found in the form of a recording left behind from the last band to record in the haunted studio in which the Foos have now occupied.
