“Radiation” is one of the year’s best under-the-radar post-punk tracks, a meditation on bad waves coming from your TV. It rises slowly and persistently in intensity until it gets to Scanners-grade, head-exploding pressure. Washington, DC, band Priests are responsible, and their live show has more knives hidden up sleeve. Brooklyn trio Household are another under-sung group doing interesting things with wobbly melodies and sharp angles. Their 2012 record, Items, has only improved with distance.
