When a duo comes in making this much noise before they've even put out their debut album, you pay attention. Index are clearly not interested in easing anyone into what they do, and "Dissolve" sounds like more of that uncompromising experimental hardcore energy that's made their singles so far feel genuinely unsettling in the best way. If you're after music that challenges rather than comforts, Vis Inertiae dropping this Friday might just be one of those albums that demands your attention on Cledvibes Radio.
