From the horses mouth: "NO keyboards, NO female singers and NO violins and other bullshit – this is ultra heavy doom from the underground. A fucking tribute to bands like Cathedral, Electric Wizard, Crowbar, Sleep and Eyehategod."
That quote leads me to believe that they have the Reverend Bizarre approach to doom metal, and that isn't far removed from the truth. They have a retro-progressive approach to doom, essentially playing Iommi-esque riffs with more of a razor like sharpness to them. They slow it down, let the guitars wail for as long as they can before progressing to the next part of the riff. Rinse and repeat, you've got yourselves Heavy Lord. The vocals kind of sound like Tom G Warrior if he got really high, and you know, I can hear a bit of the Celtic Frost gallop in some of the riffs, albeit played at doomish pace, not unlike the newest effort from Warrior and his crew.
The formula may seem simple, and perhaps sound boring, but nothing could be further from what this band delivers. It's kind of like a Tarantino flick. Tarantino doesn't necessarily bring anything new into his pictures, a lot of his movies are essentially over-wrought tributes to old gangster films, martial arts films, and samurai movies; but goddammit they fucking work. He smears the lens a bit, he produces it in such a way that it's as though we've never seen it before which makes us forget that we have. The analogy works perfectly for Heavy Lord. They're Sabbath, they're EyeHateGod, they're Cathedral, they're Electric Wizard; and they're Crowbar and they're Sleep; but they're also just Heavy Lord and proud of it.
