Act 1: Eternal Sunshine (The Pledge)

Act I: Eternal Sunshine (The Pledge) is the debut mixtape by American rapper Jay Electronica, self-published onto MySpace on July 2, 2007. The mixtape plays as one 15-minute track, sampling five different tracks of American record producer Jon Brion's 2004 film score, Eternal Sunshine of the Spotless Mind. The mixtape covers a range of themes and subjects, including hip hop, Islam, and unidentified flying objects. It is notable for its lack of drums.

The mixtape features a spoken word opening from Jay Electronica's frequent collaborators Just Blaze and Erykah Badu. Jay Electronica began recording Act I: Eternal Sunshine (The Pledge) with his built-in laptop microphone before completing it in Detroit. It has received critical acclaim for its experimentation and has since been described as Jay Electronica's breakout project. A follow-up album titled Act II: Patents of Nobility (The Turn) leaked on October 4, 2020, but his debut album, A Written Testimony was released instead in 2020, nearly thirteen years later.
