By now, you should have watched Metal Lords on Netflix already. If you haven't, get to it — it tells the funny, coming-of-age story about the drama that ensues in a high-school metal band, and Rob Halford, Kirk Hammett, Scott Ian and Tom Morello make cameos. D.B. Weiss — a.k.a. one of the dudes behind HBO's smash Game of Thrones adaptation, and a legit metalhead who got did all he could to make GoT as metal as possible — wrote and co-produced the flick with Peter Sollett (Nick & Norah's Infinite Playlist) in the director's chair and Morello tapped as Executive Music Producer.
Now, Morello has dropped a fun promo for the movie that sees the Rage Against the Machine guitarist giving a minute-long crash course through the history of heavy metal. A mere 60 seconds is, of course, way too brief a span to really cover metal's twisted journey from Black Sabbath's evil tritones to 2022's chaosphere of sprawling subgenres, but Morello gives it his best shot. Watch below.
