Kirk Hammett's debut solo EP Portals, inspired by a range of music from classical to horror movie soundtracks, is out on April 23 for Record Store Day via Blackened Recordings. "This music was created with what I describe as an Audio-Cinematic approach. They're soundtracks to the movies in your mind," says Hammett. The four-track instrumental EP was produced by Hammett and mixed by Hammett and Bob Rock. The ocean blue LP comes with a download card.
