Despite his long career as a member of Metallica, and occasional guest spots on other artists’ records, Portals will be Hammet’s first ever full solo release. It consists of four instrumental tracks, described in a release as “a collection of gateways to myriad musical and psychic destinations. Recorded in multiple locales ranging from Los Angeles to Paris to Oahu, Portals is both the result of musical and metaphysical journeys. An invitation to inner worlds accessible only by music and the psyche it fuels.”

Hammett added: “This music was created with what I describe as an Audio-Cinematic approach. They’re soundtracks to the movies in your mind.”

The EP will be released via Blackened Recordings on the next Record Store Day, 23 April, with a simultaneous release on Digital and CD. Exclusive to Record Store Day will be an ocean-blue vinyl pressing of the EP, which includes a digital copy.
