The album title itself is perhaps a reference to a line of dialogue spoken by the character of Mabel Longhetti (Gena Rowlands) in the 1974 John Cassavetes post-modern drama A Woman Under the Influence. Having just seen her children taken off to school by their grandmother, Mabel states, "All of a sudden I miss everyone; I don't know why.". Another strong possibility is that the title refers to a famous The Catcher In The Rye quote during its 26th (and last) chapter. As narrated by its lead character Holden Caulfield: "All I know about it is, I sort of miss everybody I told about.".

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. They were beckoning mountains with a brown grass love. 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. I always found in myself a dread of west and a love of east. Where I ever got such an idea I cannot say, unless it could be that the morning came over the peaks of the Gabilans and the night drifted back from the ridges of the Santa Lucias. It may be that the birth and death of the day had some part in my feeling about the two ranges of mountains.

The album artwork is by a frequent collaborator Esteban Rey.
