The Propaganda Machine is a battle cry delivered in the language of extreme metal. On Sahil Makhija’s fourth solo album as Demonstealer, he takes aim at the right-wing politicians, racist nationalists, disinformation artists, and religious extremists who manipulate and exploit the masses, in his native India and all over the world. He doesn’t mince his words; just about every lyric on the album could easily be printed on a protest sign.
