"Portals" is Kirk Hammett's first solo EP, released April 13, 2022 via Blackened Recordings.

This project consists of four instrumental tracks, described in a release as "a collection of gateways to myriad musical and psychic destinations." The songs were recorded between 2017 and 2020 in multiple locales ranging from Los Angeles to Paris to Oahu.[6] Hammett added: "This music was created with what I describe as an Audio-Cinematic approach. They’re soundtracks to the movies in your mind." An official video for the EP's third track "High Plains Drifter" was released on April 22, 2022. My personal favorite would be "The Jinn"
