It was discovered following Strummer's death that he was an archivist of his own work, having barns full of writings and tapes. Over 20,000 items were stored in the Joe Strummer archive and on 28 September 2018, a 32-song compilation album titled "Joe Strummer 001" was released. The album, which was overseen by Strummer's widow, Lucinda, and producer Robert Gordon McHarg III, features 32 songs, 12 of which have never been released. The set spans Strummer's career from the 101ers to the Mescaleros and features some unheard demos from the Clash following the departure of Mick Jones, along with an unreleased song recorded by Jones and Strummer in 1986. The set also features two of Strummer's final recordings.
