Mathcore band Mattachine and synthcore band Mikau–who both share members with screamo band Infant Island–are releasing the split EP Eject Modernity, Erase Tradition on 2/24 via Acrobat Unstable. There’s two new songs by each band, plus this collaborative song. Both bands already make delightfully chaotic music on their own, and that’s even more true when they come together. “Unlucky Channel” has everything from mathgrind fury to glitchy electronics, all topped off by the back-and-forth screams of Alexander Rudenshiold and John Irby. - Andrew Sacher for Brooklyn Vegan
