Written by frontman Chris Cornell, "Fell on Black Days" was released as the final single from the band's fourth studio album, Superunknown (1994).

"[4] Guitarist Kim Thayil has said that Soundgarden usually did not consider the time signature of a song until after the band had written it, and said that the use of odd meters was "a total accident.

The demo version is in fact a completely different song, featuring different lyrics (with only the chorus containing similarities to "Fell on Black Days") and different music, with a slightly heavier DGDGBE guitar tuning.

The Vampire Diaries featured the song in the season 6 episode "Black Hole Sun" which in turn was named after Soundgarden's hit.

[9] The black-and-white video consists of a filmed live performance of the band in a studio, with Brendan O'Brien producing the recording.

The video version of the track can be found on the "Fell on Black Days" single, Songs from the Superunknown, and the Deluxe Edition of the band's 2010 compilation album Telephantasm.
