Death Letter contains songs from their entire discography reworked for acoustic guitar.

[2] Death Letter was presumably recorded sometime prior to the band's farewell tour, which spanned several cities in 15 shows.

The EP features reworked songs from Alexisonfire's previous albums, specifically Old Crows/Young Cardinals, Crisis and Watch Out!.

A press release from Dine Alone Records said that the EP contained six old Alexisonfire tunes reworked by guitarists Wade MacNeil and Dallas Green at Jukasa Studios in Ohsweken, Ontario, without involvement of the three other members of the band.

This included a vinyl entitled Death Letter – Bonus Tracks, which features two previously unreleased acoustic renditions of the band's singles: "Boiled Frogs" and "The Northern", which were originally recorded for the Death Letter EP.
