All of a Sudden I Miss Everyone is the fifth studio album by American post-rock band Explosions in the Sky, released on February 20, 2007.

[2] The album title itself is likely a reference to a line of dialogue spoken by the character of Mabel Longhetti (Gena Rowlands) in the 1974 John Cassavetes film A Woman Under the Influence.

The title of the song "The Birth and Death of the Day" appears in the 1952 novel East of Eden by John Steinbeck:I remember that the Gabilan Mountains to the east of the valley were light grey mountains full of sun and loveliness and a kind of invitation, so that you wanted to climb into their warm foothills almost as you want to climb into the lap of a beloved mother.

The Santa Lucias stood up against the sky to the west and kept the valley from the open sea, and they were dark and brooding-unfriendly and dangerous.

The band appeared on Late Night with Conan O'Brien on February 20 and performed a shortened version of "Welcome, Ghosts".
