An air of strange saturates in the new four-song demo from Inside Voices. Steered by the omnipresent push of percussion and the commander-control, dispensed vocals in a space-station setting, an over-arching intensity hangs in the atmosphere – one that lies dormant and then is realized in switch-flipping, musical reactions that tip the scales. It’s a gradual swell of heaviness that asserts its stake on a shoegazing headspace.
