Ion Dissonance

Mathematical chaos from Montreal. Apparel, vinyl, and collectibles that channel Ion Dissonance’s precision and aggression.

Since the early 2000s, Ion Dissonance have been at the cutting edge of mathcore — marrying dizzying technical riffs with sheer sonic violence. Albums like Breathing Is Irrelevant, Solace, and Cast the First Stone show their evolution from relentless, chaotic bursts to crushing, groove-heavy assaults, all without losing their unpredictability.

Their music isn’t just heavy — it’s calculated chaos. Off-kilter rhythms, jagged time signatures, and vocals that cut through like a buzzsaw make Ion Dissonance a band you don’t just listen to… you experience.

What’s in the collection:

• Tees & hoodies with designs as sharp and intricate as their riffs.

• Caps & headwear for subtle, everyday representation.

• Vinyl for hearing every jarring stop-start in full analog detail.

• Collectibles & accessories to complete your mathcore arsenal.

We’re about quality you can feel — fabrics that last, prints that hold up, and sizing that’s accurate.

Whether you’ve been breaking your neck to their chaotic breakdowns since day one or just stumbled into the world of mathcore, this is where you find merch as uncompromising as Ion Dissonance’s sound.
