If there's one defining characteristic of The Ninth Wave, its how the fast-rising Glasgow four-piece mix light and dark. Sonically, they shake the walls. Its dissonance purified. On paper, they could be the kind of band who'd turn decibel levels up at shows just to mess with peoples heads. But there's a pop pulse running through the songs on new EP Reformation. For every bolt of raw noise, there's a sugar coating.
