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, a hip-hop record, 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, and is notable for its lack of drums. It also 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) was recorded from 2010 to 2012, but remained unreleased until it leaked on October 4, 2020. His debut album, A Written Testimony, was released instead in 2020, nearly thirteen years later. The mixtape would later be re-released on the 18th of September, 2025, alongside its sequel.
