Before you go to one of Jucifer’s shows, make sure you can cope with a 15-speaker wall. Metal lovebirds Ed Livengood and Gazelle Amber Valentine care about rock and want to make sure you do, too. With a sludge-laden sound and battling angelic and demonic vocals, the Georgia-born band has dedicated itself to the metal life. Since 2000, the pair has taken to the road permanently, preferring to live in an RV and constantly tour instead of having a home base. In a city where many bands consider themselves a part of the DIY scene, Jucifer fits right in when it comes to screaming truth to power. Livengood and Valentine also have a penchant for specifically calling federal Washington out on its mishegoss. Their 2014 album, District of Dystopia, served as that prophetic message, breaking down this town’s faults. If you’re having an especially rough time living in the District, a Thursday night with Jucifer might set you right. Jucifer performs with Stonewalled at 7:30 p.m. at the Black Cat Backstage, 1811 14th St. NW. $10. (202) 667-4490.
