The Lost Files is the first compilation album by American rapper Ski Mask the Slump God. The compilation consists of 29 songs released between 2014 and 2021 that were initially unavailable commercially, with most having been available only on SoundCloud prior to the albumâÂÂs release. The compilation features guest appearances from fellow rappers XXXTentacion, Lil Pump, Denzel Curry, Craig Xen and Pollari. The project was supported by three singles in collaboration with XXXTentacion: "Broly", "Fatality" and "IWatchedHimDrown". The compilation was released on July 30, 2025 through Very Rare & Co and Empire Distribution.
The Lost Files marked Ski Mask the Slump GodâÂÂs first project following his signing with Empire Distribution and his first release under his new label, Very Rare & Co. The album compiled previously released tracks from earlier in his career that had not been made available on major streaming platforms. The compilation album was originally marketed as a 30-track project, however, the song âÂÂFreddy vs. Jasonâ with XXXTentacion was removed at the last minute due to unresolved sample-clearance issues.
