The only problem with Metallica’s new song, “The Lords of Summer,” that they debuted on Sunday (16) in Bogota, Colombia was the quality of the audio. Regardless of how many camera angles there were, an iPhone can only capture live audio so well. Thankfully, Metallica have remedied that by releasing a “Garage Demo” version of the song. Even as a demo version, it sounds great. It’s purposely a little raw, but it’s the clearest it’s ever sounded. Also, you can now purchase the Colombia show on MP3.
